How many of the smaller cubes have at least one side painted?

Therefore all 64 smaller cubes have atleast one face exposed. Since all the sides of the two pieces are painted (either red and green). 8 smaller cubes in each piece which have one face painted. Hence, “16” is the correct answer.

How many cubes have no coloured face at all?

When the cube is cut in half, each piece will have 2 layers of 16 smaller cubes each. Therefore all 64 smaller cubes have atleast one face exposed. Since all the sides of the two pieces are painted (either red and green), no small cube has any side which is not coloured. Hence, option 4 is the correct answer.

How many cubes on each side of a cube are painted?

For 1 side painted, we look for the faces of the cube. A cube has 6 faces. 5 faces each having (12-2)*(12-2) = 100 cubes will have one side painted. We’ll have to include those cubes on the edges linked with an unpainted face. 10 cubes on each of those edges will have 1 side painted. Therefore,…
