How many cubic feet of water must be pumped from the basement? FT3

How many gallons of water are represented by the answer in part (a)? GAL

Answer 1

40/12 by 70/12 by 18/12 = 3 1/3 feet by 5 5/6 feet by 1 1/2 feet

volume = 40 x 70 x 18 = 50400 cubic inches = about 30 cubic feet

50400/12^3 = almost 30

total gallons = 50400/288 = 175 US gallons
