Excavation Volume
Cubic yards of soil for a sloped excavation.
Example
You enter
- Length (ft) 10
- Width (ft) 10
- Depth (ft) 5
- Side-slope angle (deg, 90 = vertical) 90
You get
- Volume 500 ft^3
- Cubic yards 18.52 cy
- Top dimensions 10
- Top width (ft) 10
- Set back (ft) 0
Details, formula, and sources
Volume = L × W × D plus side-slope swell volume for OSHA-compliant slopes (Type A / B / C per OSHA 29 CFR 1926 Subpart P).
