How many cubes have exactly once face painted red? Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! So in terms of cubes the prism is 6 cubes high, 3 cubes wide, 2 cubes deep.
That's a total of cubes.
The eight corner cubes (C) have three sides painted.
The twenty edge cubes (E) have two sides painted.
The eight inner cubes (I) have one side painted. so all cubes are accounted.
