Question

An empty swimming pool is to be filled to the top. The pool is shaped like a rectangular prism with 10 length, 8 width, and 2 depth. Suppose water is pumped into the pool at a rate of 20m cubed per hour. How many hours does it take to fill the empty pool?

Answer 1

Answer: 8 hours

Explanation:

The total volume of the poll is 10 * 8 * 2 = 160 m^2. If the pool is being filled at a rate of 20 m^2 per hour, then it will take 160 / 20 = 8 hours to fill the pool.
