If you have a calculator, it is simplicity itself. But if not, there is no simple way. You can use trial-and-improvement, but even that becomes cumbersome when you have a number with three or more non-zero digits.

Numerical methods, like Newton-Raphson will also become very difficult.

To cube a number, you would multiply the number three times. The cube root is the root of the number before it is multiplied. For example, 2 times 2 times 2 is 8, so the cube root is 2.

How to Find cube root of a number?

You can find a cube root by guessing which two root numbers the number comes exactly in between. Then you can decide which root number is closest to it or guess and check to find the number that cubes to it. like the cube root of 27 would be 3. 3 to the power 3 = 27. There is no formula for calculating roots of numbers. It is done by a series of approximations. x^(1/3) = exp (ln (x)/3)
