Formula and methodology
Formula: one-hole volume=π(diameter/2)²×depth; total=one-hole volume×count×(1+waste).
The ideal cylinder is a useful first estimate for posts, footings, or sampling holes. Soil sides rarely remain perfect cylinders, so the waste/over-excavation allowance should reflect the site.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Hole diameter — minimum 1.0E-6; maximum 1000
- Hole depth — minimum 1.0E-6; maximum 1000
- Number of holes — minimum 1; maximum 100000
- Waste/over-excavation (%) — minimum 0; maximum 100
Worked example
| Input | Value |
|---|---|
| Hole diameter | 0.3 |
| Hole depth | 0.8 |
| Number of holes | 6 |
| Waste/over-excavation (%) | 10 |
Waste-adjusted volume≈0.3731 m³.
Assumptions and limits
- Diameter and depth use one consistent length unit.
- Holes are treated as identical vertical cylinders.
- The result does not design a footing, reinforcement, frost depth, or shoring system.
