We have two boxes, and the volume of a rectangular prism (like a box) is equal to its length multiplied by its width multiplied by its height. Therefore, the first box has volume 2 • 4 • 4 = 32 cubic feet, and the
second box has volume 3 - 2 - 6 = 36 cubic
feet. Adding these volumes together, we get a total volume of 68 cubic feet
