The Formula
Volume = Length x Width x Depth (convert inches to feet). Weight = Volume x Density. Tons = Weight / 2000.
Why It Matters
You want a gravel driveway section 30ft wide and 50ft long at 4 inches deep. You need 18.5 cubic yards of gravel — about 28 tons. At $50/ton delivered, the total cost is ~$1,400.
