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 941192, unit digit must be 8 (8³ is 512)

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