Trick to find cube root of a number.

Method and Calculation:-

 • Find the unit digit of cube root by looking at unit digit of given number.

For cube root of 50653, unit digit must be 7 (7³ is 343)

 • Find other digit(s) by ignoring the last three digits of number and looking at remaining digits.
