Check the Divergence Theorem [itex]\int_V(\nabla\cdot\bold{v})\,d\tau=\oint_S\bold{v}\cdot d\bold{a}[/itex]

using the function [itex] \bold{v}=<y^2, 2xy+z^2, 2yz> [/itex] and the unit cube below.

Now when I calculate the divergence I get

[itex](\nabla\cdot\bold{v})=2y+2x+2y[/itex]

but Griffith's says that it is 2(x+y)

before I continue, I need to know what the heck I am missing?
