Question

An aquarium is to be drained. The aquarium is shaped like a rectangular prism with length 40 in, width 22 in, and height 16 in. Suppose

water is pumped out of the aquarium at a rate of 704 in per minute. If the aquarium starts completely full, how many minutes does it take
to empty the aquarium?

Answer 1

9514 1404 393

Answer:

20 minutes

Explanation:

The volume is given by ...

V = LWH

V = (40 in)(22 in)(16 in) = 14,080 in³

If water is removed at the rate of 704 in³/minute, the time to remove it all is ...

t = quantity/rate = (14,080 in³)/(704 in³/min) = 20 min

It takes 20 minutes to empty the aquarium.
