Hello there,
Gauss Lawstates that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux in an area isdefinedas the electric field multiplied by the area of the surface projected in a plane and perpendicular to the field.

According to the Gauss law, the total flux linked with a closed surface is 1/0 times the charge enclosed by the closed surface.

Hope this answer helps you.
Thank you!!
