On the left face (3 cm by 2 cm) the magnitude of the electric field E 1 is 310 volts/meter, and on the right face the magnitude of the electric field E 2 is 1040 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.
