Find the resistance between the points a and b for the resistor network shown.

The Attempt at a Solution
I changed to 3D cube into a 1D square and each side of the square contains 3r because each side of the cube contains an r(for each line it has up side, middle side and the down side)
http://s5.tinypic.com/2chu7hk.jpg
opposite line: 1/3r+1/3r=(3r+3r)/(9r^2)
and there are two sets of opposite line and we add them together
the final answer I got is (12r)/(18r^2)
I am wondering is it the right way to solve this problem?
any comment or help would be great. thank you very much
