A rectangular box has length 8 inches and width 4 inches with volume 64 cubic inches. What is the height?

Explanation:
Volume of a rectangular box is found by multiplying its length, width, and height. Here the length is 8 inches and the width is 4 inches, so the base area is 8 × 4 = 32 square inches. To reach a volume of 64 cubic inches, the height must satisfy 32 × height = 64, so height = 64 ÷ 32 = 2 inches. Checking quick possibilities: height 1 gives 32, height 3 gives 96, height 4 gives 128; only height 2 yields 64.
