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.
1 square km of gravel
9.26 cubic yards for every inch of depth.
16.36 cubic yards.

There are 9 square feet in a square yard... 5008 / 9 = 556.44 square yards 556.44 x $27 = $15,024
about 71 cubic metres of gravel i think
Ten cubic feet will do the job!
It depends on the depth you want the gravel to be and also how much you are charged per cubic yard. However, you will need a minimum of 2,565.5 cubic yards of gravel if you use a 4-inch depth to cover 1,800 square feet. This equates to roughly 28.5 tons of gravel.
You will need about 3.7 cubic yards (around 4.75 tons) of gravel.
You'll need about 28.704 cubic yards (37 tons) of gravel.
Plan on about 2.2 cubic yards (2.8 tons) of gravel.
You will need about 463 cubic yards (around 594 tons) of gravel for this area.
