How many yards of sand to cover a 60 foot round pen with 3 inches of sand?

Answer 1

To calculate the amount of sand needed, first convert the dimensions to yards. A 60-foot round pen has a radius of 30 feet, which is 10 yards. The area of the circle is πr², so the area is approximately 314.16 square feet. To cover it with 3 inches (0.25 feet) of sand, multiply the area by the depth: 314.16 sq ft x 0.25 ft = about 78.54 cubic feet. Since there are 27 cubic feet in a cubic yard, divide by 27 to get approximately 2.91 cubic yards of sand needed.
