cost of gravel driveway per foot
Using the previous driveway example, 300 square feet multiplied by .5 gives 150 cubic feet of gravel. To get the cost of gravel, multiply the number of cubic feet you need by the cost per cubic foot. In the example, we need 150 cubic feet; if it costs $10 per cubic foot, then the gravel costs $1,500. If your gravel supplier sells gravel in cubic yards, divide the number of cubic feet by 27 to get the number of cubic yards, then multiply by the cost per cubic yard.
