Question

A tub is shaped like a rectangular solid, with internal measurements of 2 feet x 2 feet x 5 feet. If two faucets, each with an output of 2 cubic feet of water per minute, pour water into the tub simultaneously, how many minutes does it take to fill the tub completely?

Answer 1

$V=whl$
$V=2*2*5$
$V=20$

Therefore, given the rate of 2 cubic feet per minute, it would only take 10 minutes to fill the rectangular prism with a volume of 20 cubic feet.
