Measure the length and width of your driveway in feet. Multiply the length by the width to get surface area and divide the result by three because 4 inches is 1/3 of a foot. You now have the volume of gravel needed in cubic feet. Divide the volume in cubic feet by 27 because there are 27 cubic feet in a cubic yard.

Multiply the total number of inches for the gravel depth by the total square feet from the previous step. For example, using a gravel depth of 3 inches, convert the inches to feet, which equals 0.25. Multiply 120 square feet by a gravel depth of 0.25 feet to equal a volume of 30 cubic feet.
