Now consider a cube... Charge inside the cube is 'q'. ..Total surface are of cube is 6*a*a(a is length of edge of cube). ..The total flux through the cube is q/epsilon...
q/epsilon is the flux for 6 faces...Therefore for one face the flux will be q/6epsilon..
Thanks

According to gauss law,¢=q÷€Then centre the whole is present in the cubeSo, Total flux is ¢=q/€For each surface of cubeFlux=q/6€We device it by 6because the flux is partially passing through 6 sides of the cube

As the charge is placed at the centre of one face so the flux through that face should be zero(as it is considered going parallel to that plane surface).Now the total flux is 5q/6epsilion not ,and it going to get divided into 5 equals parts so 1/5 part of the total flux will pass from one face of cube because that total flux is only for 5 faces so it should be q/6epslion not.(when total flux  divided by 5)
