Let F = = (x, y, z) (x² + y² + z²)3/2 Use the fact that V F = 0 when (x, y, z) following surfaces. (0,0,0) to find the flux of F through the The square with corners (1, 1, 1), (1, −1, 1), (−1, 1, 1), and (-1, -1, 1), oriented upward. Hint: Use the fact that this is a face of a cube centered at the origin.
