\frac{q}{24e}

total flux contributed by the charge=q/8e

because the the field lines emerging from the charge are parallel to three surfaces which it touches( remember field lines are vectors which emerge in all directions possible, try to visualize 3D) the flux through these surfaces =0.

hence the flux is passing through only three faces.

therefore flux through one surface is 1/3 times q/8e=q/24e
