Question: 500

20. If a rectangular swimming pool has a volume of 16,500 cubic feet, a uniform depth of 10 feet, and a length of 75 feet, what is the width of the pool, in feet?

A. 22
B. 26
C. 32
D. 110
E. 1,650

Correct Answer: A


A For this question, you need to know that volume equals length × width × height. You know that the volume is 16,500, the depth, or height, is 10, and the length is 75. Just put those numbers in the formula: 16,500 = 75 × w × 10. Use your calculator to solve for w, which equals 22.
