As `oversetto E ` is directed along x-axis, hence flux by the faces of the cube lying in x-y and x-z planes is zero.. Further as field is uniform one, for faces lying in y-z plane, flux is positive for one face and equal but negative for second face. Therefore , net flux through the cube will be zero.
