The cube of a binomial is as follows:
(a+b)³ = a³+3a²b+3ab²+b³

We just need to use the pascal triangle to look for the coefficients:
0:                   1
1:               1      1
2:            1     2      1
3:         1    3      3     1
4:      1    4     6      4     1
5:   1    5    10    10     5     1
