Answer 1

A cube is painted blue on two adjacent surfaces and black on the surfaces opposite to blue surfaces and green on the remaining faces .Now the cube is cut into 216 smaller cubes of equal size.

A) 56B) 48C) 32D) 64

Answer:   D) 64 

Explanation:

We know that Cubes with no surface painted can be find using (x−2)3x-23, where x is number of cuttings. Here x=6.

 ∴ (6−2)3=64

Answer 2

Answer:   D) 64 

Explanation:

We know that Cubes with no surface painted can be find using (x−2)3, where x is number of cuttings. Here x=6.

 ∴ (6−2}3=64
