First, Convert all numbers to yards. 60 feet = 19.9 (rounded to 20) yards. 8 inches = .21 yards. Then, its straight math. The volume of a cylinder (or the volume of sand in an 8 inch by 60 foot round pen), = (3.14) x radius of the circle, squared, or (10 x 10) x height (.21).
The answer to your question is : 65.9 cubic yards of sand.
That said, I think that is probably more sand than you need in a round pen. I probably would go with about 3-4 inches. Just a thought. Good luck.
