							Hi

as w know from gauss law flux thruogh the cube if charge is placed on one of its corner

= q/8(epsilon)

but if u consider the feces of cube ABCD ,ADEH ,HDCG these all r perpendicular to the charge placed so electric field lines will b perpendicular to these faces

so all the flux will b passng thru the faces  ABFE , EFGH , & BCFG


AND allthese faces are symmmtrical to charge so , equal amount of flux will b pasing thru all these i.e  {q/8(epsilon)}/3

=  q/24(epsilon)   (form every of three faces mentioned above)
