3. A Rubik's cube, with its 8 corner small cubes bitten off by a mouse (as shown in the figure). When coloring the surface of this solid figure, the number of small cubes with 4 faces colored is $\qquad$, the number of small cubes with 1 face colored is $\qquad$, and the number of small cubes with 0 faces colored is $\qquad$ (Note: You will only get points if all answers are correct, please be careful and double-check).





Please note that the actual figure is not provided in the text, so the visual reference is assumed to be available in the original context.
【Answer】 $12 ; 6 ; 1$

【Solution】Simple coloring problem. You can first mark the number of colored faces for each block on the easiest layer to see. There are 4 faces colored for 4 blocks on the top layer, 4 blocks on the middle layer, and 4 blocks on the bottom layer, totaling $4 \times 3=12$ (blocks). For 1 face colored, there is 1 block on each of the top, bottom, left, right, front, and back layers, totaling 6 blocks. For 0 faces colored, there is just 1 block in the very center.
