Volume Calculation - Based on Division of Square Method

As we have seen in the previous section that although average method is very easy, it nullifies the cutting and filling if both cutting and filling are there in a given project. To reduce such errors, division of square method is used.  This method also has the same limitation as that of an average method, but here since the whole data is divided into smaller blocks, nullifying effect is applicable to only those blocks where there is cutting and filling, and hence this method reduces the error to a great extent.
