Answer 2

Answer:

The answer is 9

Step-by-step explanation:

If you consider a normal 3x3 cube, assume the top and bottom to be yellow, front and back to be black, and the right and side to be green. Now if you cut the cube in 3 identical cuboids, the cuts being parallel to the right and left side, you have 3 faces, technically if we cut this individual 3 cuboids we get 27 cubes, but since we don't need the green part we can discard it, and now if we cut the only cuboid which remains we get nine cubes.
