公式
## How to Calculate Sand Needed ### Formula **Cubic Yards = (Length × Width × Depth in feet) / 27** **Tons = Cubic Yards × 1.35** Sand weighs approximately 2,700 lbs (1.35 tons) per cubic yard. Weight varies with moisture content and sand type: dry sand is about 1.3 tons/cu yd, damp sand about 1.4 tons/cu yd.
计算示例
A sandbox area 20 ft by 10 ft with 2 inches of sand.
- 01Depth in feet: 2 / 12 = 0.167 ft
- 02Volume = 20 × 10 × 0.167 = 33.33 cu ft
- 03Cubic yards = 33.33 / 27 = 1.23 cu yd
- 04Tons = 1.23 × 1.35 = 1.67 tons
常见问题
How much does a cubic yard of sand weigh?
A cubic yard of sand weighs approximately 2,700 pounds (1.35 tons). Wet sand is heavier, up to 3,000+ pounds per cubic yard.
What type of sand should I use?
For paver bedding, use coarse concrete sand. For sandbox play, use play sand (washed and screened). For mixing concrete, use sharp sand. For leveling, use mason sand.
How deep should sand be under pavers?
Use a 1-inch layer of sand as a bedding layer under pavers, over a compacted gravel base of 4-6 inches.
