From the Angle of mathematics:Can be cut each slice approximate as cylinder, volume for area multiplied by the height, set up the first piece of wafer volume I to V (I) (I)=k * area (I), k (I) for the wafer level, area (I) for the area, so when the chip of the total number of n tends to infinity, volume V is to sum the integral (vi)
Python's point of view, is the summation: volume=sum (the thickness of the thin skin * area)
