A 2x2x2 cube is to be constructed using 4 white and 4 black unit cubes. How many different cubes can be constructed in this way?

(Two cubes are not different if one can be obtained by rotating the other.)

Thanks for answering but apparently, the answer is 18...

I am not sure how that is the case as your reasoning makes sense.

My original answer was 8.
