Answer 2

Given that,

The number is 10648.

We need to calculate the cube root

Using estimation method

Firstly, we divided in two groups of the given number

First group = 648

Second group = 10

We need to calculate the unit digit  

Using first group,

The unit digit of 648 is 8.

$8=2^3$

So, the unit digit of cube root will be 2.

We need to calculate the 10's digit

Using second group

$8>10>27$

$2^3>10>3^3$

Now, we choose the smaller number that is 2 as our 10's digit

Hence, The cube root will be 22.
