Alfredo Maynard · Answer 1

8

Step-by-step explanation:

Only the innermost 8 1-inch cubes would have no red paint on any face.

Keyla · Answer 2

8 cubes

Step-by-step explanation:

so since all the cubes on the outside have red on it, we need to subtract 56 (the total number of cubes on the outside) from 64 (the total number of 1 inch cubes that fit in the 4 inch cube) to get 8. or you can just imagine it in your head to see a 2 by 2 by 2 cube and multiply that to get 8
