If you paint a solid wooden cube completely blue, and then cut it into 27 smaller, identical cubes, how many of those smaller cubes will have blue paint on exactly two of their faces?
12
Cubes with exactly two painted faces are the edge cubes (excluding the corners). Since a cube has 12 edges and one edge cube per edge sits between the two corners, there are 12 such cubes.
