Question

How many smaller cubes have only yellow colour face(s) ?

• A. 20
• B. 16
• C. 12
• D. 8
• E. 4

Answer 1

Answer: (D)

8

64 small cubes are cut from the bigger cube, hence each face will cut out to 16 small cubes.
The cubes lying in the middle of the face will have only one face painted. There are 4 such cubes. Since the big cube is painted in yellow on two faces, there will be total 8 small cubes with only one face painted yellow.
