what is the surface integral in gauss 's law. and what is the meaning of premittivity of free space

The electric flux linked with a surfac in an electric field my be defined as the surface integral of the electric field over the surface..
ΦE = ∫ E.ds
1.)Thus, permittivity relates to a material's ability to transmit (or "permit") an electric field.
permittivity of free space €o= D/E in free space
E----->is measured volts per metre
€o = 1/c2 µo
c is the speed of light in free space
μ0 is the magnetic constant.
