Methods of computing the volume of earth work
Trapezoidal formula method
This formula provides an extension of mean sectional area method. In other words the trapezoidal formula method and mean sectional area methods are one and the same. Let A1, A2, A3 ……………An be the cross sectional area of earth work at the section along the given line.
Let “D” be the distance between any two adjacent sections. Then the total volume of earth work along the given section can be computed from the relation.
V = D/2 (A0+An+2(A1+A2+A3+ ………………..+An-1)
