Formula and methodology
Formula: Volume = length x width x depth in feet x (1+waste); mass = volume x bulk density.
The density is explicit because gravel type, moisture, and compaction can change tons per cubic yard substantially.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Length — ft; minimum 0.1; maximum 100000
- Width — ft; minimum 0.1; maximum 100000
- Depth — in; minimum 0.1; maximum 120
- Waste allowance — %; minimum 0; maximum 50
- Bulk density — lb/ft^3; minimum 1; maximum 300
Worked example
| Input | Value |
|---|---|
| Length | 20 |
| Width | 10 |
| Depth | 4 |
| Waste allowance | 10 |
| Bulk density | 100 |
The tool reports cubic feet, cubic yards, and approximate US tons.
Assumptions and limits
- Length and width are feet; depth is inches.
- Bulk density is supplied by the user or material vendor.
