## How to Calculate Gravel Needed
### Formula
**Cubic Yards = (Length × Width × Depth in feet) / 27**
**Tons = Cubic Yards × 1.4**
Gravel weighs approximately 2,800 lbs (1.4 tons) per cubic yard. This can vary from 1.3 to 1.5 tons depending on the type and moisture content.

计算示例
A driveway 30 ft long, 10 ft wide, with 3 inches of gravel.
- Depth in feet: 3 / 12 = 0.25 ft
- Volume = 30 × 10 × 0.25 = 75 cu ft
- Cubic yards = 75 / 27 = 2.78 cu yd
- Tons = 2.78 × 1.4 = 3.89 tons
