A. (1/2) x (1 1/2) x (3/4) = (1/2) x (3/2) x (3/4) = 9/16
The product is the same as the volume found by packing the prims with unit cubes.
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
A. 1/2 x 11/2 x 3/4
B. 1/2 x 1/2 x 3/4
C. 1/2 x 3/2 x 3/4
D. 1/2 x 3/2 x 3/2
