Question

A swimming pool is to be drained. The pool is shaped like a rectangular prism with length 25 feet, wide 20 ft, and depth 4ft. Suppose water is pumped out of the pool at a rate of 125^3 per hour. If the pool starts completely full, how many hours does it take to empty the pool?

Answer 1

Answer: 5 hours 30 minutes

Step-by-step explanation: 25x20x4=2000, meaning the pool is 2,000 feet.

for the next part you have to do 125x3=375

now we have to guess the number of hours it takes to pump out the water from the pool which would be 375x5.5=2,000 meaning your answer is 5.5 hours or 5 hours 30 minutes.
