Euler formula for geometric modeling faces, holes I don't know if I'm in the right place to ask this question!

I have two 3D modeling and I want verify the Euler-Poincaré Formula on them that include face,holes, vertex, etc. Anyone knows about that?
It is not entirely clear what you are asking, but the Euler formula is
V - E + F = 2 (1-g), where g is the number of holes (the genus).
Perhaps you also have cavities? Then look at this San José State exposition.
