Use the image to answer the question.
An illustration shows a 3 D rectangular cuboid segmented into multiple blocks. It shows two adjacent sets of a 3 row by 6 column grid. The width is start fraction 1 over 2 end fraction, the length is 1 start fraction one over 2 end fraction, and the height is start fraction 3 over 4 end fraction.
Multiply the edge lengths of a right rectangular prism with length 12 , width 112 , and height 34 to show that the product is the same as the volume you found by packing the prism with unit cubes with an edge length of 14 inch.
Cube method:
Number of cubes: 36
Volume of each cube: 14×14×14=164
Volume of the prism:
v=36×164
=3664
=916 cubic units

To find the volume of the right rectangular prism made up of 4 cubes that are 15 inches on each side, we can use the cube method:
Number of cubes: 4
Volume of each cube: 15 x 15 x 15 = 3375 cubic inches
Volume of the prism:
4 x 3375 = 13500 cubic inches
Reducing the answer to lowest terms:
13500 ÷ 100 = 135
13500 ÷ 125 = 108
Therefore, the volume is 108 cubic inches.
The correct response is:
108 cubic inches
Number of cubes: 4
Volume of each cube: 15 x 15 x 15 = 3375 cubic inches
Volume of the prism:
4 x 3375 = 13500 cubic inches
Reducing the answer to lowest terms:
13500 ÷ 100 = 135
13500 ÷ 125 = 108
Therefore, the volume is 108 cubic inches.
The correct response is:
108 cubic inches

To find the volume of the right rectangular prism with length 13 m, width 14 m, and height 21/2 m, we use the formula:
Volume = length x width x height
Volume = 13 x 14 x 21/2
Volume = 13 x 14 x 21/2
Volume = 182 x 21/2
Volume = 382/2
Volume = 76 cubic meters
Reducing the answer to lowest terms, we get 76 cubic meters.
Therefore, the correct response is:
76 cubic meters.
Volume = length x width x height
Volume = 13 x 14 x 21/2
Volume = 13 x 14 x 21/2
Volume = 182 x 21/2
Volume = 382/2
Volume = 76 cubic meters
Reducing the answer to lowest terms, we get 76 cubic meters.
Therefore, the correct response is:
76 cubic meters.
