Question

I arrive home to find that my 55 foot by 35 foot basement has 18 inches of water in it.

a) If 1 cubic foot of water is about 7.48 gallons, how much water will I be pumping out of my basement?
Express your answer rounded to the nearest tenth of a gallon.
gallons

Answer 1

To find the volume of water in cubic feet, you would multiply length x width x height. All the measurements need to be in the same units, so multiply 18 inches x 12 inches/foot = 1.5 feet. Then to find volume, multiply 55 feet x 35 feet x 1.5 feet = 2887.5 cubic feet of water. To convert cubic feet to gallons, multiply by 7.48. 2887.5 x 7.48 = 21598.5 gallons, rounded to the nearest tenth of a gallon.
