SUMMARY
The net electric flux through a Gaussian surface is invariant to the shape of the surface, as established by Gauss' Law. When a positive test charge is placed at the center of a spherical Gaussian surface, replacing it with a cube of the same volume or a cube with one third the volume does not alter the net flux. This is due to the spherically symmetric nature of the electric field around the charge, ensuring that electric field lines passing through the center remain consistent regardless of surface shape.
