Test: Cubes and Dice- 1 - Question 1

### A cube is coloured orange on one face, pink on the opposite face, brown on one face and silver on a face adjacent to the brown face. The other two faces are left uncoloured. It is then cut into 125 smaller cubes of equal size. Now answer the following questions based on the above statements. How many cubes have at least one face coloured pink?

Detailed Solution for Test: Cubes and Dice- 1 - Question 1

If the cube is cut into 125 smaller cubes, how are the cuts made? 4 cuts/slices in x, y, z– planes respectively. So the cube is a 5 × 5 × 5 cube. That is, it has 5 squares on each of its faces.
So if only one face is painted pink, how many cubes have at least 1 face colored in pink? It is the number of cubes with only one side colored in pink because pink is only colored on one face. So, the answer would be: 5 ∗ 5=25
