Volume of a closed surface (divergence theorem)

Click For Summary
SUMMARY

The discussion centers on the calculation of the volume of a closed surface using integral calculus, specifically referencing the Divergence Theorem. The user seeks a formula analogous to Green's Theorem for area calculation, highlighting that while Green's and Stokes' theorems apply to surface integrals, the volume calculation is more complex. A proposed formula for volume, V, is presented as V = (1/3)∬_S (xdydz + ydzdx + zdxdy), which the user questions for correctness.

Green's and Stokes' theorems can by used on surface integrals, just like they are used for 2-D integrals.

The math is a little more complex, however.

Google: 'line surface and volume integrals'
 
I am searching for something similar to this:

EDIT: I think that the volume can be calculated by:
V=\iint_{S}\!\!\!\!\!\!\!\!\!\!\!\subset\!\supset xdydz = \iint_{S}\!\!\!\!\!\!\!\!\!\!\!\subset\!\supset ydzdx = \iint_{S}\!\!\!\!\!\!\!\!\!\!\!\subset\!\supset zdxdy = \frac{1}{3}\iint_{S}\!\!\!\!\!\!\!\!\!\!\!\subset\!\supset (xdydz+ydzdx+zdxdy)

Correct?

This equation is really correct?
