Solution
The correct option is A 8
Since the cube is divided into 125 pieces then u can imagine it as cut into 5 slices horizontally and vertically resulting in 5x(5x5) pieces.
Suppose Brown is B, Orange is O, Pink is P and Silver is S.
n(P + S) = 4
n(O + S) = 4
Total is 8. Hence, the correct answer is (A).
