Question

Is a cube a Gaussian Surface?

Answer 1

Gauss's law is true for any closed shape, such as a sphere, cuboid, cube, and other closed surfaces. To measure the electric current of a given charge the charge must be spread evenly.

Yes, a cube is a Gaussian surface.

1. A three-dimensional Gaussian surface is a closed surface.
2. It approximates the flow of a vector field, which is usually a gravitational field, electric field, or magnetic field.

Hence, a cube is a Gaussian surface.
