Hey MATE!
If their are 64 cubes then the bigger cube has dimensions :
4×4×4
Now the cubes having 2 faces outside would be the ones kept on edges in the middle .
Let us consider 1 face which would have 8 cubes with 2 - faces also same would be the case of side opposite to that of taken phase has 8 such peices.
So now we know about 2 out of 6 faces hava a total of 8 + 8 = 16 cubes.
Now talking about the other 4 faces all would have only 2 pairs left so the number of cubes left =>
2 + 2 + 2 + 2 = 8
Therefore total cubes with 2 faces shown =
16 + 8 = 24 Answer
Soory for the untidy figure.
Hope it helps
