Tell me more about the number "6"? is that feet or inches?
Yes, to calculate the amount of gravel needed for a slab, you can use the formula: Volume = Length × Width × Depth. First, measure the dimensions of the area where the slab will be placed, then convert these measurements into the same unit (e.g., feet or meters). Multiply these dimensions to get the volume in cubic feet or cubic meters. Finally, since gravel is typically sold by the cubic yard, convert the volume from cubic feet or meters to cubic yards by dividing by 27 (for cubic feet) or 1.31 (for cubic meters).
218.75 cubic feet or 8.1 cubic yards
A "yard of gravel" is a measure of volume, not a measure of area. There are 27 cubic feet (3x3x3 feet) in a yard of gravel, or one cubic yard.
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.
92.593 cubic yards for every inch deep.
9.26 cubic yards for every inch of depth.
Plan on about 2.2 cubic yards (2.8 tons) of gravel.
Knowing that 1 cubic foot is pretty much equal to 100 pounds or 0.05 ton, 1 ton of gravel is around 20 cubic feet.
You will need 20 cubic yards or 25.7 tons of gravel.
12x75 x how deep you want it (expressed in decimal form) ie .5 for 6`` = cubic feet. Divide that answer by 27 and you have cubic yards and that is how you order it.
486 cubic feet
3000 sq ft * 4 inches = 1000 cubic feet.
