I calculate cube root of any number by hand or even mentally.

Ex. To find cube root of say n= 723456.

723456 = 723.456*1000

Cube root of 723456 = cube root of 723.456 * 10

Cube root of 723.456 ?

Make an estimate of the root.

Preferably an integer by which you can easily divide the given number.

10^3 = 1000.

So root is less than 10.

Let the estimate be 9.

723.456/9 = 80.384

80.384/9 = 8.93156

Take average of 9,9 and quotient 8.93156.

It is 8.97718

Cube root of 723456 = 8.97718*10 = 89.7718.
