hiding back face line of wireframe model

have made a wireframe model. So lines on back faces are visible.

Now i need that no line on back face should be visible. Can any 1 help me in geting out of this.

Thanks in advance.

Expecting a favourable reply

Actually i dont need to cull the faces, what i need is whn i see my 3d shapes from any view it shd look as a whole ( not culled) and at the same time
the lines on back faces should not be visible.

So the geometry should not be affected but only the lines on back faces should be hidden from any view.
