Question

How many smaller cubes have one face green and one of the adjacent faces black or red?

• A. $8$
• B. $16$
• C. $24$
• D. $28$

Answer 1

The correct option is C $24$

Suppose top and bottom surfaces are green surfaces.
So on a surface only one side painted box are 4 so remaining 12 are painted green$+$either red or black .
and we have 2 green surfaces.
So answer is$=12\ast 2=24$
Hence, option 'C' is correct.
