Direction: 216 cubes of similar size are arranged in the form of the bigger cube (6 cubes on each side, i.e.., 6 x 6 x 6) all the exposed surfaces are painted.
-
How many of the cubes have 2 most faces painted?
-
- 144
- 125
- 96
- None of these
Correct Option: C
Since total number of cubes is hence in the formula we will substitute n = 6
Number of the cubes with 2 faces painted is 6(6 - 2)2
= 6 x 16 = 96
