Formula
The geometry matches the gravel page. The density does not:
tons = length × width × depth / 12 × 100 / 2000
100 pounds per cubic foot is a dry-sand planning figure. Gravel on this site uses 105.
Assumptions
- The sand is dry and loose.
- Depth is inches. Length and width are feet.
- A ton is 2,000 pounds.
Worked example
A 10 by 10 foot area at 6 inches of dry sand weighs 2.5 t.
Input definitions
- Dry sand
- Sand that has not been given the extra weight of water in the voids.
Limitations
Washed, damp, or compacted sand can weigh more. Use the supplier's density when you have it.
Questions
Why is sand not the same as gravel?
This page uses 100 pounds per cubic foot. The gravel page uses 105 for loose crushed gravel.
What is 6 inches of a 10 by 10 area?
Fifty cubic feet. At 100 pounds each, that is 5,000 pounds, or 2.5 tons.
