"http://wiki.answers.com/Q/How_much_crushed_gravel_for_eighteen_square_feet_by_four_inches_deep" 6 cubic feet. With Gravel weighing 95 pounds per cubic foot, you will need approximatly 570 pounds of gravel Four inches is 1/3foot so 18sq.ft x 1/3ft=6cu.ft. You usually buy gravel by the cubic yard which is 3ftx3ftx3ft=27cu.ft so you only are looking at 2/9 cu.yd
18sq.ft is only 4ftx4-1/2ft. so is not much area to cover. Weight varies by type of gravel.
Convert the inches to feet (dividing by 12), then multiply. The result is then in square feet.
about 71 cubic metres of gravel i think
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
The question as stated makes no sense, as square feet is a measure of area and "yard", is a measurement of volume. Normally, "yard" is a measurement of length. However, concrete, soil, gravel, sand, etc., are normally sold (in the U.S.) by the "yard" which is simply short for "cubic yard." However, you may easily calculate the area that a yard of crushed rock will cover, depending on the desired depth of crushed rock. As a cubic yard is 3 feet by 3 feet by 3 feet, which is equivalent to 9 square feet by 36 inches, simply divide 36 inches by the desired depth in inches, and multiply it by 9 square feet. Thus, if you wanted a depth of 8 inches, 36 divided by 8 is 4.5. So, you can cover 4.5 square yards, or 4.5 times 9 square feet = 40.5 square feet, which would be a square area approximately 6 feet 4 inches by 6 feet 4 inches.

To cover 300 square feet 4 inches thick, you would need approximately 3 cubic yards of gravel.
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.
