Depends on what depth you want to spread the gravel at.
This answer depends on knowing the cubic capacity of 50 lbs. 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.
You'll need about 28.704 cubic yards (37 tons) of gravel.
To determine the amount of gravel needed, first convert the depth from inches to feet: 2 inches is approximately 0.167 feet. The volume of gravel required can be calculated by multiplying the area (8 ft x 8 ft) by the depth: 64 sq ft x 0.167 ft = 10.67 cubic feet. Therefore, you will need about 10.67 cubic feet of gravel to cover the area 2 inches deep.

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.
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.

3000 sq ft * 4 inches = 1000 cubic feet.
A 50 lb bag of gravel typically covers about 0.5 cubic feet. To determine how many square feet it covers at a depth of 4 inches (which is 1/3 of a foot), you can use the formula: area = volume / depth. Therefore, a 50 lb bag of gravel would cover approximately 1.5 square feet at a depth of 4 inches.
2800 feet of gravel
Gravel averages 100 pounds per cubic foot or 20 cubic feet per ton. That's depth x width x length. So if you want to cover something 6 inches deep, you can cover 40 square feet of surface.
A yard of pea gravel typically covers an area of about 100 square feet at a depth of 3 inches. If spread more thinly, such as at 2 inches deep, it can cover approximately 150 square feet. The exact coverage can vary based on the size of the gravel and how densely it is packed. Always consider the desired depth when calculating coverage.
