Tapered log volume
Estimate geometric solid volume from both end diameters.
How this works
Treat each log as a conical frustum: πL(D₁² + D₁D₂ + D₂²)/12.
Example
Using the example inputs, geometric solid volume is 0.290597 m³.
- Log length
- 3 m
- Large end diameter
- 0.4 m
- Small end diameter
- 0.3 m
- Log count
- 1
- Geometric solid volume
- 0.290597 m³
Scope and assumptions
Not a lumber grading or sawmill board-foot scale; bark and irregularities affect yield.
