Homework Statement
show that the volume enclosed by a closed surface S is given by## \frac{1}{3} \int_{S} \vec{x} \cdot d\vec{A} ##
Homework Equations
divergence theoremThe Attempt at a Solution
using divergence theorem
I get that ##V =\frac{1}{3} \int_{V} \nabla \cdot \vec{x} dV ##
but I want
## V = \int_{V} dV ## don't I? how does it simplify?
