To determine how much gravel you need for a 300 square foot area, you'll first need to decide on the desired depth of the gravel layer. Common depths range from 2 to 4 inches. For example, if you want a 3-inch depth, you would convert that to feet (3 inches = 0.25 feet) and multiply: 300 sq. ft. x 0.25 ft = 75 cubic feet. Since there are 27 cubic feet in a cubic yard, you would need about 2.78 cubic yards of gravel for that area.
To calculate the amount of gravel needed, first convert the dimensions to consistent units. The area is 13 feet by 9 feet, which equals 117 square feet. The depth of 4 inches is equivalent to 1/3 of a foot. Therefore, the volume of gravel required is 117 square feet × 1/3 foot = 39 cubic feet.
about 71 cubic metres of gravel i think
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.
I need to know how thick the layer of gravel is meant to be.
1 square km of gravel
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.

Depends on depth of gravel you plan to put down. For each 1 inch depth: Estimate gravel having a density of 2.7. 150 x 1/12 x 62.4 x 2.7 = 2106 pounds (slightly more than 1 ton) so if you want 3 inches of gravel you need about 3 tons of gravel
You will need about 3.7 cubic yards (around 4.75 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.
16.36 cubic yards.
An 8-foot wide by 90-foot long by 8-inch depth requires a minimum of 2,565.5 cubic yards (22.8 tons) of gravel.

1 square foot = 144 square inches, so 100 square ft = 14400 sq inches. Multiply be 3 = 43200 cubic inches. I believe gravel is normally sold by the cubic yard. 1 cubic yard = (36 in)3 = 46656 cubic inches. So 43200/46656 = 0.926 cubic yards
