Rectangular prisms are three-dimentianal model that have six rectangular faces, with three sets of two congruent sides. To illustrate the concept in more concrete terms, you tin make a simple model of a rectangular prism using construction newspaper or cubic blocks.

  1. ane

    Review the dimensions. Before edifice a rectangular prism, you lot will need to know the desired length, width, and acme of that prism. Write those dimensions downwardly and refer to them throughout the procedure.

    • Example: Consider the steps you lot'll need to follow when constructing a rectangular prism with a length of 6 inches (xv cm), a width of 4 inches (10 cm), and a peak of iii inches (7.vi cm).

  2. two

    Measure out and cutting two length by width rectangles. On a sheet of heavy construction paper, use a ruler and pencil to draw two rectangles. The length of each rectangle should match the length of the final prism, and the width of the two rectangles should match the width of the final prism.[1]

    • Later on drawing both rectangles, employ the ruler to measure out them once again. Both rectangles must be equal in size and must accurately match the length and width of the rectangular prism yous wish to create.
    • Once you lot are certain that both rectangles are the right length and width, cut them out with sharp scissors.
    • Note that these two rectangles volition grade the top and bottom of your rectangular prism.
    • Example: Measure and cutting two rectangles, each with a length of 6 inches (fifteen cm) and a width of four inches (10 cm).

  3. 3

    Measure out and cut two length by meridian rectangles. Use a ruler and pencil to draw two more rectangles from heavy structure paper. The length of these rectangles should friction match the length of the rectangular prism, simply the width of these rectangles will demand to match the pinnacle of the final rectangular prism.[ii]

    • Re-measure the ii rectangles afterward drawing them to check for accuracy, then employ precipitous scissors to cut both of them out.
    • These two rectangles will eventually grade the front and back of your rectangular prism.
    • Example: Measure and cut two rectangles, each with a length of half-dozen inches (15 cm) and a width of 3 inches (7.vi cm).

  4. 4

    Measure out and cut two width by height rectangles. Sketch ii more rectangles on heavy construction newspaper using a ruler and pencil. The length of each rectangle should match the width of the rectangular prism, and the width of each rectangle should match the tiptop of your rectangular prism.[3]

    • After cartoon both rectangles, measure them again to check for accuracy before cutting them both out with scissors.
    • These two final rectangles will grade the left and right sides of the rectangular prism.
    • Example: Measure and cutting 2 rectangles, each with a length of 4 inches (10 cm) and a width of three inches (seven.6 cm).

  5. five

    Loosely tape four rectangles into a strip. Line up the length-by-width rectangles and the length-by-height rectangles, alternate back and along between the two types. Record the length sides together on one side of the paper.[4]

    • The paper rectangles should be lined upwards in the following order: length-by-width, length-past-height, length-by-width, length-by-height. Practise not place identical rectangles next to one another.
    • Note that the rectangles should be lined up then that their length sides prevarication direct next to the length side of the adjacent rectangle.
    • Apply 1 to two strips of tape to each shared border. When finished, all four rectangles should be taped together into one strip.
    • Example: Alternate the half-dozen-inch by iv-inch (15-cm by 10-cm) rectangles with the 6-inch by 3-inch (15-cm past 7.6-cm) rectangles, matching the 6-inch (15-cm) sides together. Tape the 6-inch (15-cm) sides in place.

  6. half-dozen

    Join the ends of the strip. Fold the strip so that the two unattached length-side ends meet. Utilise one or two pieces of tape to hold these two ends together.

    • As you fold, make sure that the strip is folding at the edges between separate rectangular faces. You lot may need to utilise your thumbnail to pucker the tape in betwixt these edges, making it easier to fold.
    • When done, you should have something that looks like a rectangular tube. The prism shape is almost complete, merely two sides are still missing at this point.
    • Example: Fold up the strip and record together the two loose half dozen-inch (15-cm) sides.

  7. vii

    Attach the remaining two rectangles. Position the ii remaining rectangles over the two open ends of the shape. Use record to attach all four sides of each rectangle to the matching sides of the rectangular prism.

    • Make sure that the height side of each rectangle matches the height side of the prism. Likewise, the width side of each rectangle must lucifer the width side of the prism.
    • Outset by taping 1 side of each rectangle in place, then tape the opposite side. The paper should already stay in place at that bespeak, but taping the remaining two sides will provide greater security.
    • Instance: Position the 4-inch (10-cm) sides of one rectangle against the 4-inch (10-cm) sides of the rectangular prism. The iii-inch (7.6-cm) sides should naturally match upward, likewise. Tape the rectangle in place, so repeat with the remaining rectangle.

  8. 8

    Measure the sides of the finished product. Utilise a ruler to measure all sides of the finished shape. The length, width, and height dimensions should each friction match the required dimensions yous needed to fulfill.

    • At this point, the rectangular prism is consummate.
    • Instance: The final rectangular prism should have a length of vi inches (15 cm), a width of 4 inches (x cm), and a height of three inches (7.6 cm).

  1. 1

    Review the required dimensions. You'll need to know the required length, width, and height of the desired rectangular prism before you lot can build it. Review these dimensions now and refer to them throughout the construction process.[5]

    • For the sake of simplicity, information technology might be easiest to work in generic "cubic units" instead of inches or other specific measurements. If you do wish to work in specific inches, you lot will need to apply blocks that measure 1-inch (2.5-cm) on all sides. Foursquare dice measuring i inch (2.5 cm) on all sides can be a expert option.
    • Example: Consider the steps you'll need to follow to construct a rectangular prism with a length of 4 cubic units, a width of iii cubic units, and a height of 2 cubic units.

  2. ii

    Gather enough blocks. The number of blocks y'all'll need will match the book of the final rectangular prism. To observe the volume of the rectangular prism, you will need to multiply the length, width, and superlative together.[6]

    • Note that you lot must employ cubic blocks with equal lengths, widths, and heights. Do not employ blocks of whatsoever other shape.
    • If desired, you can use a small strip of double-sided tape or another temporary adhesive to all faces of all blocks. Doing so is non strictly necessary but may make it easier to build the terminal rectangular prism.
    • Example: To calculate the book of this rectangular prism, multiply: four * three * 2 = 24
      • This signifies that yous will need 24 blocks to build this item rectangular prism.

  3. iii

    Create a line of blocks to lucifer the length. Line upward enough blocks to match the number of cubic units required for the length of the rectangular prism. Go along the line every bit fifty-fifty equally possible.

    • Example: Line upward four blocks in an fifty-fifty row.

  4. 4

    Create a second line to lucifer the width. Starting from the end of your length line, build a 2d line of blocks that matches the number of cubic units required for the width of your rectangular prism.

    • The total number of blocks in this width edge must match the width of the final prism. This will include the first block already included in the length line. In other words, the number of blocks yous will add to the structure during this stride will exist one fewer than the number of cubic units making up the width of the rectangular prism.
    • Case: Line up two more blocks off i corner of your original line, creating a new perpendicular line containing three blocks full.

  5. v

    Complete the rectangle. Construct another length and width edge to mirror and match the first 2. Fill up in the rectangular outline with as many blocks as needed to make the rectangle solid.[7]

    • Count to make sure that the length and width edges match the required length and width of the rectangular prism.
    • Yous should also count the total number of blocks used for this get-go rectangular surface. The total number of blocks should lucifer the expanse of the face, which can be calculated by multiplying the length past the width.
    • Example: Build some other four-cake length edge off the end of the start width border, and so build some other three-cake width edge between the other end of the two length edges. Fill in the space betwixt with two more blocks.
      • Summate the surface area past multiplying: 4 * three = 12
      • Count the total number of blocks in this rectangle. There should be 12 blocks full.

  6. half dozen

    Stack enough blocks to match the superlative. Starting at one corner of the completed rectangular base, stack plenty blocks to equal the required pinnacle in cubic units for the desired rectangular prism.[8]

    • As you count the number of blocks in this stack, make certain that you count the lesser block already included in the completed base. The full number of blocks in this stack must equal the total number of cubic units in the height of the prism, so the number of blocks you'll add will actually exist one fewer than the number of cubic units required for the height of the prism.
    • Instance: Place i block on top of 1 corner cake of your existing rectangle. This should set a height of ii blocks (cubic units).

  7. 7

    Repeat over the entire rectangle. Build similar stacks of blocks on tiptop of each block in the completed rectangular base. The number of blocks in each of these stacks must lucifer the number of blocks in your first stack and the required height of the rectangular prism.

    • When finished, you should not have any excess blocks left behind.
    • Example: Identify 1 block on meridian of each of the remaining 11 blocks in your original rectangle. This should use up the residue of your original 24 blocks.

  8. 8

    Count the blocks to mensurate the sides. Mensurate the sides by counting the number of blocks making up the length, width, and superlative of the rectangular prism. The blocks making up these sides must match the number of required cubic units for each side of the intended prism.

    • Note that you can also utilise these block counts to summate the surface expanse of each visible face. To summate surface expanse, yous merely need to multiply the length and width of any face up.
    • The volume of the rectangular prism can be calculated, as well, past multiplying the number of blocks making up the length, width, and height of the prism. The volume of the rectangular prism in cubic units should lucifer the number of blocks used to construct the prism.
    • Example: The length of the rectangular prism should comprise four blocks, the width should contain iii blocks, and the height should incorporate ii blocks.
      • To calculate the surface area of the front end and back faces, multiply: 4 * two = 8 units
      • To calculate the surface area of the summit and bottom faces, multiply: four * 3 = 12 units
      • To calculate the surface area of the right and left faces, multiply: iii * two = 6 units
      • To calculate the full volume of the rectangular prism, multiply: 4 * 3 * two = 24 cubic units
