Question

Q. A large cube with side 6 cm is colored red on all faces, and then is cut into small identical cubes of 1 cm side each. Now, how many small cubes will have only two faces colored?

• A. 216
• B. 48
• C. 96
• D. 8

Answer 1

The correct option is B 48

$n=\frac{6}{1}=6$

small cubes with only two faces coloured $=12(n–2)$

$=12(6–2)$

$=12\times 4=48.$
