**FOR MAKING CUBE ROOT OF A NUMBER

this formula works when the main no is in between 10 to 99

we know the cubes are as follows
1^3=1
2^3=8
3^3=27
4^3=64
5^3=125
6^3=216
7^3=343
8^3=512
9^3=729

now the cubes of 10 to 99 will be in between 1000 to 1000000
so when a no is given just take the last three digit as different and the rest of first digits as different
from the last digit of last three digit we get the last number of it's cube root
now or first digit see the first part... the fist part is greater than whose cube take that no as first digit

if we go through the example then we understand it clearly

....................................................................
EX:-
     46656= 46 656
here the last three digits 656. here the last digit is 6 which is in 6's cubes last digit
so the last digit is 6
now the rest first digits is 46
which is in just greater than 27 that means 3's cube
so, the cube root of the no 46656 is 36
