During the exam we have done a lot of calculation and some calculations are  taken too much time .
and we need to save time because some one day exam having very short time. Then we have to need some short trick for calculation.

If you know the short trick of find the cube root then you save your time and utilise another questions and score more marks.

Method of finding cube root see on following ideo.





Step of finding of cube root-
Step -1 First of all we make pairs of three three digits from right to left.

Step-2  After making pairs, we finding unit digits of number  whose cube unit digits are same as                         given number.
Step -3 Then compere the second pair, and finding smallest perfect cube number.

Step -4 Find the nearest cube root of nearest perfect cube number and write in decimal digits.
and find the cube root.

Step-5 After finding the cube root of number, check it revers.
