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:

  20 minutes

Step-by-step 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.
