@Madhavi
1^3 = 1
2^3 = 8
3^3 = 27 the unit digit is taken into consideration i.e 7.
Similarly,
4^3 = 64 the unit digit is taken into account i.e 4.
And so on... Is it fine now?

@Sangita.
Remember that very simple 1^3=1, 2^3=8, 3^3=7, 4^3=4, 5^3=5, 6^3=6, 7^3=3, 8^3=2, 9^3=9.
So 216 unit digit is 6 so guess 6^3=216.
