Average-end-area cut volume (m³)
Sum interval length × average adjacent cut/fill areas independently.
Average-end-area fill volume (m³)
Sum interval length × average adjacent cut/fill areas independently.
Symbols and units
- a
- Stations JSON [[chainage m,cut area m²,fill area m²],...]
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Sum interval length × average adjacent cut/fill areas independently.
