only Conservapedia explains math concepts well. This theorem: the overall net flux through a closed surface equals the sum of all the changes in flux throughout the volume enclosed by the surface

The '''divergence theorem''' establishes the volume integral (triple integral) of a function over a three-dimensional shape ''equals'' the double integral of the same function over the two-dimensional surface that encloses the space.

The '''divergence theorem''' establishes the volume integral (triple integral) of the derivative (divergence) of a vector function over a three-dimensional shape ''equals'' the double integral of the perpendicular component of same function with respect to a two-dimensional surface that encloses the space.

Simply put, the overall net flux through a closed surface equals the sum of all the changes in flux throughout the volume enclosed by the surface.
    
For example, the volume integral of the electric field caused by a charge within an electric sphere equals the surface integral of that same field.
