Examples
Try the starting example
- Section positions (m)
- 0,5,10,15
- Measured section areas (m²)
- 0,8,10,0
- Trapezoidal stockpile volume (m³)
- 90
Try another scenario
- Section positions (m)
- 1.0,5.0,10.0,15.0
- Measured section areas (m²)
- 0,8,10,0
- Trapezoidal stockpile volume (m³)
- 86
Calculation method
Calculation method
Trapezoidal stockpile volume (m³)
Volume=sum((x next-x)×(area next+area)/2).
Symbols and units
- a
- Section positions (m)
- b
- Measured section areas (m²)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions & limits
Assumptions & limits
- Linear interpolation between measured sections only. 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. Linear interpolation between measured sections only.
