Solution 1

n[2][2][2] is a 3 dimensional array.
n[2][2] is "only" two dimensional.

n[2][2][2] can store 8 elements.

Solution 2

n[2][2][2] is a three dimensional array.
You can consider Three dimensional array as a CUBE, This cube have 6 faces.
Each face is of dimension 2 x 2.

Hence Three dimesional array n[2][2][2]will have 8 elements in it.

The analogy to a cube is a good idea, but I feel the reference to the faces (6) doesn't really help - to stay with your analogy you will have to count the corners of a cube, not the faces.

neither the corner or faces: n[3][3][3] has 27 elements... one of them is in the middle of the cake!
