Let [math] be unit cube where each face is parameterized so that the unit normal vectors point outwards. For the vector field [math] determine if the flux across the face is positive, negative, or zero:
The flux across the face [math] is
The flux across the face [math] is
The flux across the face [math] is
The flux across the face [math] is
The flux across the face [math] is
The flux across the face [math] is
