Multiply the edge lengths of a right rectangular prism with length 1/2 , width 1 1/2 , and height 3/4 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 1/4 inch.
Cube method:
Number of cubes: 36
Volume of each cube: 1/4×1/4×1/4=1/64
Volume of the prism: v=36
×1 6/4 =36/64 =9/16 cubic units
Responses:
1/2×3/2×3/2
1/2×3/2×3/4
1/2×11/2×3/4
1/2×1/2×3/4
1/2 x 3/2 x 3/4 = 9/4 = 2 1/4
Therefore, the product of the edge lengths of the prism is 2 1/4, which is equivalent to the volume obtained by packing the prism with unit cubes.
