    A cube, painted yellow on all faces is cut into 27 small cubes of equal size. How many small cubes are painted on one face only?

    A)  1                            

    B)         6

    C)  8                            

    D)         12

    Correct Answer: B

    Solution :

    The big cube cut into 27 small cubes. Clearly, out of these 27 small cubes, the cubes having only one side painted are those which lie at the center of each face of the big cube. Since, there are 6 faces of a cube, therefore, the required number of cubes is 6.
