    Directions: A cube is painted red on two adjacent faces and black on the faces opposite to the red faces and green on the remaining faces. It is now cut into sixty-four smaller cubes of equal size.
    How many cubes have one face green and one of the adjacent faces black or red?

    A)  8                            

    B)         16

    C)  24                         

    D)         28

    Correct Answer: B

    Solution :

    There are two opposite faces painted green. Each green face has 4 sides and each will give 12 such cubes painted from 2 faces, one of which is green and the other is red or black. Thus, there are \[\text{2}\times \text{12}=\text{24}\] cubes.
