Fig 1.1. shows a closed Gaussian surface in the share of a cube of edge length 6.00 m. It lies in a region where the nonuniform electric field is given by $\vec{E} = 5.00\hat{i} + (3.00x + 4.00)\hat{j} + 7.00\hat{k}$ N/C, with x in meters. Determine:
d) Flux penetrate each side of surface.
e) Total charge contained by the cube.
