Problema Solution
Find the capacity in gallons of a rectangular tank whose base is 3 ft 4 inches by 2 ft 8 inches and with a height 5 ft 8 1/2 inches.
Answer provided by our tutors
The volume of a rectangular tank is equal to the base area of the tank multiplied by its height. Converting all lengths to inches, we have a tank whose base is 40 inches by 32 inches with a height of 68.5 inches.
Since (volume) = (base area) x (height), the tanks volume is (40 in x 32 in ) x (68.5 in) = 87680 in^3.
Since 1 cubic inch = 0.004329 US gallons, 87680 in^3 x [0.004329 gal/in^3] = 379.57 gallons.
