All the points on the bottom side of the cube has the same potential ( f1 ) , and all of the points on the top side of cube (on picture) also has the same potential ( f2 ). So, this mix of resisters is equivalent to the mix of the resisters on the picture below. Now, we can easily find that Rab=12/6 =2 .

I agree. It is not a level 3 one.

We can observe that the vertices of the bottom surface are equipotential and so are the vertices of the top surface. So, by redrawing the circuit, we get 6- 12 ohm resistances in parallel.

So answer is 2.
