You will need about 65.185 cubic yards (83.6 tons) of gravel for this area.
You'll need about 28.704 cubic yards (37 tons) of gravel.
5.55 cubic yards 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.
It would depend on how thick you want to spread it.
To cover 300 square feet 4 inches thick, you would need approximately 3 cubic yards of gravel.
You would need about 5 cubic yards. Gravel is usually sold by the ton. I do not know that conversion. Who ever would deliver it for you should be able to help. If I were using crushed concrete I would use 15 tons... but I can not spread it 1" thick either.

You would need 7.2 cubic yards of gravel to cover an area that requires that volume of material. It's crucial to ensure that you acquire the right amount to prevent any shortage or surplus during your project.
47.55 cubic yards . 4" would be 5.23 cubic yards.
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.
You would need about 13 cu yards or about 15 tons.
The amount of gravel needed to cover 252 square feet depends on how thick (that is, deep) you want the gravel. If you want the gravel to be 3 inches thick... Convert the measurement to the same units. We'll use feet. 3 inches = 1/4 foot Multiply the thickness times the area to get volume in cubic measure. 1/4 feet x 252 feet = 63 cubic feet Gravel in the US is usually sold by the cubic yard, which is 27 cubic feet Thus, 63/27 = 2 1/3 cubic yards 2 1/3 cubic yards of gravel will cover 252 square feet of area to a dept of 3 inches.
You will need about 65.185 cubic yards (83.6 tons) of gravel for this area.
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
