How many gallons are in a sixteen foot by four foot deep pool?

Answer 1

If you mean a round pool that is 16 feet in diameter and 4 feet deep, the bottom area is given by: Acircle = pi x r2 In this expression, r is the radius of the pool, which is half the diameter, or 16 / 2 = 8' Acircle = pi x 82 = pi x 64 = 201.06 square feet A cylinder (which is the shape the water takes confined in the pool) has a volume given by: Vcylinder = pi x r2 x h The only "new" variable there is h which is the height. Let's finish. Vcylinder = pi x r2 x h = 201.06 x h = 201.06 x 4 = 804.25 cubic feet There are about 7.48 gallons in a cubic foot, and if you have cubic feet to convert to gallons, you'll multiply by that 7.48, which will be 804.25 x 7.48 = 6015.8 gallons The methodology was correct, and the numbers do not lie, so yes, there is really that much water in a pool with those dimensions and that water level.
