Answer 1

A.128

Explanation:

First you break the prism apart so that you have one 7x4x2 rectangular prism and one 12x3x2 prism. Find the volume of both, then add them together.

Volume of 12x3x2:

12 x 3 = 36. 36 x 2 = 72.

Volume of 7x4x2:

7 x 4 = 28. 28 x 2=56.

Then add both volumes: 72 + 56 = 128.
