Each surface of the rectangular box shown is aligned with the xyz coordinate system. Two surfaces occupy identical rectangles in the planes x=0 and x=x₁=2.3 m. The other four surfaces are rectangles in y=y₀=1.2 m, y=y₁=5.5 m, z=z₀=1.7 m, and z=z₁=5.1 m. The surfaces in the yz plane each have area 15.0m². Those in the xy plane have area 9.9m² ,and those in the zx plane have area 7.8m². An electric field of magnitude 6 N/C has components in the y and z directions and is directed at 58° above the xy-plane (i.e. above the y axis.)
