Answer 2

Answer:

1)Estimation will be done like 10648,First we will group 648 as first group and 10 as the last group

Then last no of First group i.e 8 is a cube of 2 so first no. is 2

Then 10 is more than 2^3 and less than 3^3 so we will take 2 as the no.

So Cube root of 10648 will be 22

2)Similarly Cube root of 15625 will be 25

3)110592 cube root will be 48

4)91125 cube root will be 45
