Where figures are bounded by curves the process is usually analytical, and is based on the theorems of Pappus of Alexandria, which state:

(l) If any plane curve revolve about any external axis which lies in its plane, the volume of the solid generated is equal to the product of the area of the revolving curve and the length of the path described by the centroid of the revolving area.

(2) In the same circumstances the area of the solid thus generated is equal to the product of the perimeter of the revolving curve and the length of the path described by the centroid of the curve.

The calculation of the cubature is nothing but the measurement of the volume of a given complex and the measurement obtained is calculated in cubic meters.

## How To Calculate The Cubature?

From our basics learned, we can say that the calculation of the cubature is equal to: base x height x depth, then obviously there is to insert the specific context to analyze. Above all for the building industry, the calculation of the volume is made by multiplying the area covered by the total height of the house.

On the height, however, can often arise diatribes with the technicians for the real measure to be calculated: beyond that most of the time you use a virtual height (3 m). it is useful to always consult the NTA (Technical Implementation Rules).

As for balconies or other, in theory should not be included in the calculation but on this we must examine well the regulations on the subject that vary from municipality to municipality by also checking the maximum limits provided.
