How to make a Sand Volleyball Court?

Question:What are the dimensions? How much should it cost?

Answers:
The actual playing are is 9m x 18m or... 29' 6" x 59' 3
and leave room for a 3m (9'10") free zone around the outside of these boundaries

You need to make it about 3-4 inches thick, at the minimum. Call any company that delivers sand and tell them the dimensions and they can tell you how much (I would say at least 10 ton) and the price of the sand.
