That depends on how much sandy fill weighs per cubic yard. Do you know that?

(30*70*1.33)/27=104 cubic yards. Multiply that by how much it weighs per cubic yard and you're all set. Can you find that out? An educated guess would be 1/2 ton to the cubic yard.
Therefore, you'd need about 52 tons.

You need more info in the question

It's been over two years since the original post. Rather a moot point by now.

Dry Sand = 110Lbs/Cu Ft

About 154 Tons
