Prismoidal Volume

Earthwork volume between two cross-sections — Average End-Area V = L·(A1+A2)/2 vs Prismoidal V = L·(A1 + 4Am + A2)/6, with prismoidal correction.

Method

AEA: V = L · (A1 + A2)/2. Prismoidal: V = L · (A1 + 4·Am + A2) / 6. Prismoidal correction Cp = AEA − Prismoidal — used when only end areas are measured: V = AEA − Cp.
