A cube is made of white plastic, but the exterior surface is painted black. If the cube is cut into 125 smaller cubes of exactly the same size, how many of the smaller cubes have exactly two black sides?
For an additional challenge, identify all the remaining smaller cubes as to how many black sides they have, including those with no black sides. Your total, with those from the first part, should be 125.
