How to Find the Cube Root of a Number?

[NotaMathPerson]

Hello!

My book explained how to take cube root of a number withou using calculator. I managed to extract the cube root of number less than a million. But when its higher like this one 12812904. I cannot extract it.

Can you suggest an algorithm on how to go about this one? Thanks!

Hi NotaMathPerson,

There's a method to find the cube root of a number, similar to long division mentioned at the following webpage. It might be the one you are looking for.
