Assume that the charge is located at origin and the corner of the cube also at origin.
Using Gauss's law and symmetrical argument:
 now if we place 7 more cubes around original cube. Each face of this new cube contains 4 faces of original.
The new big cube has 6 faces placed symmetrically around origin, total= 24 faces.
now the total flux according to Gauss's law is q/epsilon0.
therefore,  flux through each face is q/24 epsilon0.
 
Thanks.
