12167
The groups are 12 and 167
167 ends with 7 and we know that if 7 is at the unit place of any perfect cube number then it's cube root will have 3 at its units place only. the digit at the units place of required cube root is taken as 3.
Now group 12,
2^3=8 and 3^3=27 also 8<12<27
2 is smaller than 3, therefore 2 is taken as the digit at tens place of the required cube root.
Thus, cube root of 12167 is 23.
