Well, I depends on how deep you want the layer of gravel to be. But, if you just want a enough gavel to cover the space I would say about 15 to 20 bags of it. Trust me, I have done the exact same thing you are about to do. (you can get the gravel bags from Lowe's for super cheap)
It depends how deep you want the gravel to cover, if you want it to be 2 inches deep it's going to cost more than 5 inches. Also it depends how big the gravel is cut, I think that the smaller the gravel is the more it costs.
Based on sand and gravel calculator found on L.R. Faulk Construction Co. site, 1 ton of gravel (clean rock) will equal approximately 7.3 sq. ft x 6 inches deep, or 5.2 sq. ft x 3 inches deep. A ton of gravel will cover approximately 15 square yards (135 square feet) at 3 inches deep.
