Step-by-step explanation:
when we divide we get 4x4x4 little cubes, so it’s 64 cubes.
The corner cubes all of them have 3 faces painted, so that’s 8 cubes.
64–8=56
The middle cubes all have 1 side only painted, and we have 4 of these for each cube face, so thats 4x6= 24
56–24=32
We have to remove the inner cubes that have no ink at all, and thats 8 cubes
32–8=24
These 24 left, all of them have 2 sides with paint!
