1. Take a cube number such as 29791 whose cube root is to be determined and start making a group of three digits starting from the rightmost digit.
2. The first group will give us the unit’s digit of the required cube root. The number 791 ends in 1, therefore, the last digit will be 1 because unit’s digit is 1 only when the cube root also ends with 1.
3. Now taking the second group, it is between 33 = 27 and 43 = 64. We take the smaller value, therefore, the digit at the tenths place is 3.
