Direct answer
Calculate the geometric volume of a defined fill zone. Earthworks require care because excavated bank volume, transported loose volume and compacted placed volume are different states.
Use the tool for simple level-raising zones or rectangular excavations where dimensions are known. Complex grading surfaces require survey or earthworks modelling.
Divide the site by depth band. For a trench or excavation with changing cross-section, calculate reaches separately. Do not use an average depth unless it is supported by measurements.
Fill dirt is not topsoil and may be governed by engineering or environmental requirements. Quantity alone does not establish acceptability.
A level area of 9 m × 6 m has two depth bands: 30 m² at 0.20 m and 24 m² at 0.35 m. Volumes are 6.0 m³ and 8.4 m³, giving 14.4 m³ of placed geometric space.
The example uses geometry only. It does not insert a density, package size, recommended depth or supplier tolerance.
Describe whether the requirement is placed volume, excavated volume or imported loose fill. Confirm suitability, testing, contamination status and conversion factors through the project process.
The calculator does not model cut-and-fill balance, shrink/swell, compaction, slopes, stability or contamination.
Not from a full terrain surface. Use appropriate survey or civil-design tools for complex earthworks.
No. Those require project- and material-specific evidence.
