Cube construction

A 2×2×2 cube is to be constructed using 4 white and 4 black unit cube. How many different cubes can be constructed in this way? ( Two cubes are not different if one can be obtained by rotating the other. )

n =  9

Step-by-step explanation:

$$\begin{gathered} n<2^{4+4} \\ n=1\cdot 1+1\cdot 4+2\cdot 2=9 \end{gathered}$$
