After a devastating rainfall, a basement floor that is 40 feet by 80 feet is covered in 18 inches of water.
00:08
Consider that one cubic feet of liquid corresponds to 7 .5 gallons of liquid.
00:14
One, what are the dimensions of the rectangular prison formed by the water? two, how many cubic feet of water must be pumped from the basement? and three, how many gallons of water is represented by your answer in part a? so if you, i've taken the liberty to draw it here, but the height that we need to use is the height of the water.
00:40
So 18 inches is our height, but also note that it's an inch as so i converted it to feet so that you get the correct answer when you multiply using our formula here for the volume of a rectangular prism.
00:56
So again, we just plug in our numbers.
00:58
Our length is 80 feet times 40 feet times 1 .5.
01:06
And this should give us 4 ,800 cubic feet of water.
01:11
So this is how much water is in the basement.
01:16
So this is our answer to question number one.
01:19
This is the dimension of the rectangular prism.
01:22
The next question that's asking is how many cubic feet of water must be pumped.
01:27
I would like to think that the owner wants to remove all of this...
