Earthwork Cross-section Area

Earthwork cross-section area can be for small or large areas.

 

Earthwork Cross-Section Area formula

\(\large{ A_c =  \frac{ 1 }{ 2 }  \;  \sum_{i = 1}^n \; x \; \left( y_{i + 1} \;-\; y_{i - 1}  \right)  }\)

Where:

Units	English	Metric
\(\large{ A_c }\) = area cross-section	\(\large{ft^2}\)	\(\large{m^2}\)
\(\large{ x_i }\) = horizontal axis	\(\large{ft}\)	\(\large{m}\)
\(\large{ y_i }\) = vertical axis	\(\large{ft}\)	\(\large{m}\)
\(\large{ n }\) = number of points on cross-section	\(\large{dimensionless}\)
