A cube 4 cm on each side is painted blue and cut into 64 one cm cubes. How many onecm cubes are painted blue on exactly two faces?

Cube Problem 
Steve,
Those would be the cubes along the edges, but not the corners.
There are 12 edges, each with 2 noncorner cubes.
So, looks like 24 cubes with 2 blue sides.
