Answer key · Set A
Length Times Width Times Height
16 The bottom layer is 3 cubes long and 2 wide: 3 × 2 = 6.
212 2 layers of 6 cubes make 12.
34 × 3 × 2 Volume is length times width times height. Adding the edges counts no cubes.
430 5 × 2 = 10 cubes in a layer, and 3 layers: 10 × 3 = 30.
5False 5 × 3 × 2 = 30. Ten is only 5 × 2, which leaves out the width.
6Box 3 Box 3 is 2 × 3 × 2 = 12. Box 1 is 18 and Box 2 is 16.
760 4 × 5 × 3 = 60.
842 The first part is 4 × 3 × 2 = 24 and the second is 3 × 3 × 2 = 18. 24 + 18 = 42.
940 8 cubes in a layer times 5 layers is 40.
101-B, 2-A, 3-C, 4-D Multiply the first two edges, then multiply by the third.
11Multiply the edges: 4 × 3 × 2 = 24. Adding edges counts no cubes. The volume is 24 cubes.
1263 The tall part is 5 × 3 × 3 = 45 and the low part is 3 × 3 × 2 = 18. 45 + 18 = 63.
