Question 473020: A tub is shaped like a rectangular solid, with internal measurements of 2 feet*2 feet*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?
Help me please. Answer by ccs2011(207) (Show Source):
You can put this solution on YOUR website! Volume is length*width*height
Rate of water coming in is 2 cubic feet per faucet.
There are 2 faucets so total amount of water coming in is 4 cubic feet per minute.
We want to know how many minutes it takes for there to be 20 cubic feet.
Divide by 4 on both sides
Therefore, it will take 5 minutes to fill the tub.
