The volume of any square, or part of a square is equal to the average
height(elevation difference) at the corners, times the area.
To compute the volume: 1- draw a line between the cut and the fill areas
2- compute the total volume
of all the complete cut squares,
do the same for the fill, use
the previous formula
3- Compute with the
incomplete squares
separately
4- Compute the difference
between the cut and the fill.,
pay attention to the expansion
factor.
