Jerry and his cubes

-
Jerry puts a cube against the floor and the walls in the corner of his room, as in diagram 1, then paints the faces that he can see. He therefore paints three faces.




In the second corner he puts four cubes in a square on the floor in the corner and then puts one cube on top in the corner too as shown in diagram 2. If he paints all the faces he can see now, how many faces does he paint on the cubes in this corner?
