Question

If it takes one hour to fill a pool with 50 ft^3 of water, how many hours will it take to fill a pool that measures 10 ft by 8 ft with a depth of 5 ft?

Answer 1

8 hours

Explanation:

10 x 8 x 5 = 400. 400 / 50 = 8. So it will take 8 hours to fill a pool with 400ft3

Answer 2

Your second pool has a volume of (10 ft)*(8 ft)*(5 ft) = 400 ft^3, which is 8 times 50 ft^3. It can be expected to take 8 times as long to fill, so 8 hours.
