How much sand is need to go under a 15 ft round pool if the sand is 1 inch thick?

Answer 1

To calculate the amount of sand needed for a 15 ft round pool with a thickness of 1 inch, first find the area of the pool's base. The radius of the pool is 7.5 ft (half of 15 ft), so the area is approximately 176.71 square feet (using the formula A = πr²). Since 1 inch is equal to 1/12 of a foot, the volume of sand required is about 14.72 cubic feet (area multiplied by thickness in feet: 176.71 ft² × 1/12 ft). Therefore, approximately 14.72 cubic feet of sand is needed.
