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'.

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.
