Cube Root of 56

Professor Greenline Explaining Math Concepts

We will learn the cube root concept to use it on other mathematical topics like algebra, mensuration, geometry, trigonometry, etc. So, it is as important as learning square roots. Let us now see how we can obtain the cube root value of 56, and its examples.

What Is the Cube Root of 56?

The cube root of 56 is the value which, when multiplied by itself three times (cubed), gives the original number 56. The cube root of 56 is 3.82586236554.  The cube root of 56 is expressed as ∛56 in radical form, where the “ ∛ ”  sign” is called the “radical” sign. In exponential form, it is written as (56)â…“. If “m” is the cube root of 56, then, m3=56. Let us find the value of “m”.

Finding the Cubic Root of 56

We can find cube roots of 56 through a method, named as, Halley’s Method. Let us see how it finds the result.

Cubic Root of 56 By Halley’s Method

Now, what is Halley’s Method? It is an iterative method for finding cube roots of a given number N, such that, x3=N, where this method approximates the value of “x”.


Formula is ∛a≅ x((x3+2a) / (2x3+a)), where


a=given number whose cube root you are going to find


x=integer guess for the cubic root


Let us apply Halley’s method on the given number 56.


Step 1: Let a=56. Let us take x as 3, since 33=27 is the nearest perfect cube which is less than 56.


Step 2: Apply the formula.  âˆ›56≅ 3((33+2×56) / (2(3)3+56)) = 3.79…


Hence, 3.79… is the approximate cubic root of 56.
