Methods of computing the volume of earth work
Mean sectional area method
Let A1 and A2 be the cross sectional areas of earth work at two given sections, which are at a distance “D” apart. Then the mean sectional area is given by,

Then the volume of earth work between the two sections is computed from the relation V = A x D.
