AP Physics C E and M

Question

A box with each edge of 1 m is centered on the origin. The total electric flux through one side of the box is 1 Nm²/C. What is the total charge inside the box?

Answer 1

According to Gauss' Law, the flux through each surface of a cube is equal to the charge at the center of the cube. A cube has six surfaces, so if the flux through one surface is 1 Nm^2/C, the charge inside the cube is equal to 6 C.
