To find the cube root of a number without a calculator, a long division-like method can be employed, which is effective for numbers both below and above one million. The user is struggling with extracting the cube root of 12,812,904 specifically. A suggested resource provides a detailed explanation of this method. Utilizing this algorithm can help in calculating cube roots for larger numbers. Mastering this technique allows for manual extraction of cube roots efficiently.

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!
