How many gallons of water in 8 x 26 pool?

Explanations:

The volume of a rectangular prism is equal to the length times the width times the height. In this case, the length is 8 feet, the width is 26 feet, and the height is 5 feet. So, the volume of the pool is 8 x 26 x 5 = 1040 cubic feet. One cubic foot of water weighs 62.4 pounds. So, the weight of the water in the pool is 1040 x 62.4 = 65,088 pounds. One gallon of water weighs 8.34 pounds. So, the number of gallons of water in the pool is 65,088 / 8.34 = 7,808 gallons.
