Answer:
The given question is not fully correct .
I will give u another eg ...
If a cube is painted red and cut into 64 pieces .
Approach this question as ,,
64 pieces = 4 *4* 4 so take n=4
just use this formula
1. no sided painted =(n-2)^3
2. 1 sided painted =6 * (n-2)^2
3. 2 sided painted = 12 *(n-2 )
4. 3 sided painted = always 8 (a cube has 8 corners)
