Question

A cardboard square, 2 feet on each side, has 3 inches square cut out of each corner so that an open box can be constructed. Find the volume of the box in cubic inches.

Answer 1

When the four new flaps are folded up, the remaining square is 12-3-3=6 inches on a side, and the height is 3 inches.

Thus, the volume is 6*6*3=108 cubic inches (base area multiplied by height).
