How many gallons of water in a 10ft by 30inch swimming pool?

Answer 1

11000

Answer 2

This is a question of volume. Assuming the pool is round and is 10 feet in diameter and 30 inches deep or high, we can apply the formula for volume of a cylindrical shape: V = pi r2 h. Since the diameter is 10 feet, the radius is half that or 5 feet. To make sure our answer comes out right, we also have to use the same units of measurement for everything. So we will convert 5 feet to 5 x 12 = 60 inches. V = 3.14 x 602 x 30 = approximately 339,120 square inches of water. With 1728 square inches in a square foot (12 x 12 x 12), this comes out to about 196.25 square feet of water. Converting to gallons, there are about 7.48 gallons of water in a cubic foot of water, so 196.25 x 7.48 = about 1468 gallons of water in the pool.
