如何运用“三面涂色在顶点 两面涂色棱中间 一面涂色在面上 没有涂色心里面”的技巧---**Question Stem:** 用棱长1cm的小正方体拼成如下的大正方体，把它们的表面分别涂上颜色。三面涂色、两面涂色、一面涂色以及没有涂色的小正方体各有多少个？ **Other Relevant Text:** (Boxed text with "月亮点睛") 三面涂色在顶点 两面涂色棱中间 一面涂色在面上 没有涂色心里面 **Chart/Diagram Description:** Type: Diagrams of cubes made from smaller unit cubes. Main Elements: 1. A large cube, appearing to be 4x4x4 small cubes. It is a solid block representation. 2. Three separate small unit cubes. 3. A bottom row of diagrams: * A 3x3x3 cube structure with the corner unit cubes highlighted in yellow. * A 3x3x3 cube structure with the unit cubes along the edges (but not corners) highlighted in yellow. * A 3x3x3 cube structure with the unit cubes in the center of each face highlighted in yellow. * A structure formed by stacking unit cubes, resembling the inner part of a cube with the outer layers removed. Some of these inner cubes are highlighted in yellow. The diagrams illustrate the types of unit cubes within a larger cube based on how many faces are exposed on the surface (and thus colored). The boxed text provides hints on the location of these types of cubes: 3 faces colored at vertices (corners), 2 faces colored along edges (not corners), 1 face colored on faces (not edges or corners), and no faces colored inside. The initial large cube (4x4x4) is likely the main subject of the question regarding the number of cubes with different numbers of colored faces. The subsequent diagrams (3x3x3 examples and the inner structure) illustrate the concept for smaller or partial cubes.
