Formula and methodology
Formula: Net volume = length×width×depth; order volume = net×(1+waste/100); mass = order volume×bulk density.
The order allowance is applied to geometric volume before the entered bulk density estimates mass.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Driveway length — m; minimum 0; maximum 1000000
- Driveway width — m; minimum 0; maximum 1000000
- Gravel depth — m; minimum 0; maximum 1000000
- Bulk density — kg/m³; minimum 1.0E-6; maximum 1000000
- Waste allowance — %; minimum 0; maximum 1000
Worked example
| Input | Value |
|---|---|
| Driveway length | 20 |
| Driveway width | 3 |
| Gravel depth | 0.1 |
| Bulk density | 1600 |
| Waste allowance | 10 |
Order volume = 6.6 m³; mass ≈10,560 kg.
Assumptions and limits
- Dimensions are metres, depth and waste are nonnegative, and bulk density is positive.
- The driveway is a uniform rectangular prism with one bulk-density assumption.
- Compaction, subgrade, drainage, edging, slope, delivery, and structural design are not modeled.
