On the left face (3 cm by 2 cm) the magnitude of the electric field E 1 is 320 volts/meter, and on the right face the magnitude of the electric field E 2 is 1030 volts/meter. On the other faces only the direction is known (horizontal). Calculate the electric flux on every face of the box, the total flux, and the total amount of charge that is inside the box.
