Find the capacity in gallons of a rectangular tank whose base is 3 feet 4 inches by 2 feet 8 inches and with a height 5 feet 8 1/2 inches.

Solution:

3 feet 4 inches = 10/3 feet

2 feet 8 inches = 8/3 feet

5 feet 8 1/2 inches = 5.708 feet

Volume = L*W*H = 10/3 * 8/3 * 5.708 = 50.74 cubic feet

1 cubic feet = 7.48 gallons

So capacity = 50.74*7.48 gallons = 379.58 gallons
