Now, let's multiply the edge lengths of the rectangular prism by 1/2, 1 1/2, and 3/4:
Length: 1/2
Width: 3/2 = 1 1/2
Height: 3/4
Product of edge lengths: (1/2) x (3/2) x (3/4) = 9/16
This product is the same as the volume we found by packing the prism with unit cubes, which is 9/16 cubic units.
Multiply the edge lengths of the right rectangular prims with the 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 prims with the unit cubes as the edge length of 1/4 inch
cube method:
number of cubes: 36 cube
Volume of each cube:1/4 X 1/4 X 1/4 = 1/64
volume of prims:
v = 36 x 1/64
= 36/64
= 9/16 cubic units
