Flux will be Q divided by 8 epsilon. According to gauss law, flux is one by epsilon times the total charge enclosed by the surface. In this case charge is paced at vertex.  To enclose the given charge we have to place seven cubes around the given cube. 

Flux passing through these eight cubes is Q divided by epsilon. So flux passing through one of the cube is 1/8 of Q by epsilon.
