1. The problem statement, all variables and given/known data Find the flux of F over the surface of the cube with vertices [tex]( \pm 1, \pm 1, \pm 1)[/tex] using the outer normal. F(x,y,z)=(x+y)i+zj+xzk 2. Relevant equations Flux of F over S is [tex]\iint F \cdot n dS[/tex] 3. The attempt at a solution I think the normal should be 1 in the respective directions for each side of the cube, and I keep getting 0 when I try to work out the math.
