Earthwork Volume by End Area Method
Earthwork volume between two cross-sections by the average-end-area method.
Average-end-area overestimates between dissimilar sections (it ignores the waist) — highways pay by it anyway, by convention. The prismoidal correction is your negotiation card.
Formula
Earthwork Volume by End Area Method is a free average end area method for surveyors, civil engineers and property buyers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Earthwork Volume by End Area Method
Earthwork volume between two cross-sections by the average-end-area method. The calculation implements V = L·(A₁+A₂)/2; prismoidal: L/6·(A₁+4A_m+A₂) (Surveying texts; highway earthwork measurement). Average-end-area overestimates between dissimilar sections (it ignores the waist) — highways pay by it anyway, by convention. The prismoidal correction is your negotiation card.
