A cube of side 12 cm is painted green on all the faces and then cut into smaller cubes of sides 2 cm each. Find the number of smaller cubes that have only one face painted.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 96.
A cube of side 12 cm is painted green on all the faces and then cut into smaller cubes of sides 2 cm each. So, length of each smaller cube = 12 / 2 = 6
So, the number of smaller cubes having only one face painted = 6(Smaller cube length - 2)2 = 6(6 - 2)2 = 6(16) = 96
