Answer:

12 cubes have exactly two faces painted green.

Step-by-step explanation:

Given:

3 faces painted red

3 faces painted green

Number of pieces = 27

Therefore, the cubes having 2 faces green are:

• From face 1 :

4 small cubes will have 2 green faces.

From face 2 :

4 small cubes will have 2 green faces.

From face 3 :

4 small cubes will have 2 green faces.

Therefore, total number of cubes that has exactly 2 green faces

= 4 + 4 + 4

= 12

Therefore, 12 cubes have exactly two faces painted green.
