pls give me the different patterns of cube and cube roots

Observe the following pattern of sums of odd numbers:
                                    1 = 1 = 1³
                             3 + 5 = 8 = 2³
                    7 + 9 + 11 = 27 = 3³
        13 + 15 + 17 + 19 = 64 = 4³
21 + 23 + 25 + 27 + 29 = 125 = 5³
