The figure below shows a closed Gaussian surface in the shape of a cube of edge length 2.10 m, with one corner at x1 = 5.00 m, y1 = 4.00 m. The cube lies in a region where the electric field is given by E→ = (−3.00i^ − 4.10y2 j^ + 3.00 k^) N/C, where y is in meters. What is the net charge contained by the cube? C
