The cube root of 192 is the value that, when multiplied by itself three times (cubed), gives the original number 192. Do you know? Cube roots apply to our real life also, like that for measuring volume and scaling, density and mass calculation, etc.

What Is the Cubic Root of 192?

The cube root of 192 is 5.76899828123. The cube root of 192 is expressed as ∛192 in radical form, where the “∛"  sign is called the “radical” sign. In exponential form, it is written as (192)⅓. If “m” is the cube root of 192, then, m3=192.  Let us find the value of “m”.

Finding the Cubic Root of 192

The cube root of 192 is expressed as 4∛3 as its simplest radical form, since


 192 = 2×2×2×2×2×2×3


∛192 = ∛(2×2×2×2×2×2×3)


Group together three same factors at a time and put the remaining factor under the ∛ .


∛192= 4∛3


 We can find cube root of 192 through a method, named as, Halley’s Method. Let us see how it finds the result.
 

Cubic Root of 192 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 192.


Step 1: Let a=192. Let us take x as 5, since, 125 is the nearest perfect cube which is less than 192.


Step 2: Apply the formula.  ∛192≅ 5((53+2×192) / (2(5)3+192))=5.757 


Hence, 5.757 is the approximate cubic root of 192.

Problem 2

The Volume of a cube is 192 cubic centimeters, find the length of one side of the cube.

Okay, lets begin

We know that, (side of a cube)3=Volume of a cube


⇒side of the cube =  ∛(Volume of the cube)


⇒side of the cube = ∛192


⇒ side of the cube = 5.768 cm


Answer: 5.768 cm
 

Explanation

We applied the formula for finding the volume of a cube, and inverted it to find the measure of one side of the cube.
