Figure above shows a closed Gaussian surface in the shape of a cube of edge length 3.0 m. There exists an electric field given E =[(2.0x+4.0)i+8.0j+3.0k]N/C., where x is an metres, in the region in which it lies. The net charge in coulombs enclosed by the cube is equal to

The total electric flux through any closed surface is proportional to the total electric charge inside the
surface.
