The figure below shows a closed Gaussian surface in the shape of a cube of edge length $2.10$ m, with one corner at $x_1 = 5.00$ m, $y_1 = 4.00$ m. The cube lies in a region where the electric field is given by $\vec{E} = (-3.00\hat{i} - 4.20y^2\hat{j} + 3.00\hat{k})$ N/C, where y is in meters. What is the net charge contained by the cube? C
