The formula for volume of a sphere is πr²h. The diameter is 14 ft, and the radius is 1/2of the diameter, so the radius is 7. The depth is the height, which is h. Now, substitute the known values into the expression:

π*7²*2

49π*2

98π is the exact amount of sand needed to fill the sandbox, and the approximate value is 307.87608.
