According to me;

4(n1- 2) + 4(n2- 2) + 4(n3- 2) = 4(4- 2) + 4(3- 2) + 4(5- 2)=24 is the answer.

According to me, the Answer is 24.

4(n1-2) + 4 (n2-2) + 4(n3-2).
n = 4.
4*2 + 4*1 + 4*3 = 24.

Yeah, it should be 20.

Answer should be 20 as it is not written 'only two colours'.

SIKARI said:   8 years ago
The answer should be 20.

Here nothing is written about other face colour.

So it should not matter whether it is coloured or not so I think 20 is answer.

What is the correct answer? please explain it.

The answer would be 20 if the question contains the phrase "at least two faces coloured with red and green". Since at least is not there hence the answer is 12.
