You will need about 463 cubic yards (around 594 tons) of gravel for this area.
You would need approximately 2.5 cubic yards of gravel to cover a 12' by 15' area at a depth of 2 inches.
You would need about 13 cu yards or about 15 tons.
You cannot directly convert cubic yards to square yards because they measure different things: volume vs. area. Cubic yards measure volume, while square yards measure area. To find how many square yards cover the same area as a cubic yard of gravel, you would need to know the thickness or depth of the gravel layer.
That depends on how deep you want to spread it. To cover 600 square feet, you need (111/9) cubic yards for every 6 inches of depth.
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)
