Question

Estimate the weight of water in pounds in a fish tank with width 14 ft, length 32 ft, and height 24 ft. The density of water is about 8.33 pounds per gallon. One gallon of water is approximately 0.134 cubic feet. Round to the nearest tenth.

Answer 1

Find the volume of the tank by using the equation V = l x w x h

Volume =  14 x 32 x 24 = 10,752 cubic feet

now calculate the number of gallons by dividing total cubic feet by 0.134:

10,752 / 0.134 = 80,238.81 gallons

now multiply the number of gallons by the weight per gallon:

80,238.81 x 8.33 = 668,389.287 pounds

rounded to nearest tenth = 668,389.3 pounds total
