The cube root of 36 is the value that, when multiplied by itself three times (cubed), gives the original number 36. Do you know? Cube roots apply to our real life also, like that for measuring dimensions, density and mass, field of engineering etc.

What Is the Cube Root of 36?

The cube root of 36 is 3.30192724889. The cube root of 36 is expressed as ∛36 in radical form, where the “ ∛ “  sign is called the “radical” sign. In exponential form, it is written as (36)⅓. If “m” is the cube root of 36, then, m3=36. Let us find the value of “m”.
 

Finding the Cube Root of 36

The cube root of 36 is expressed as ∛36 as its simplest radical form,

since 36 = 2×2×3×3


∛36 = ∛(2×2×3×3)


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


∛36= ∛36 


 We can find cube root of 36 through a method, named as, Halley’s Method. Let us see how it finds the result.
 

Cube Root of 36 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 36.


Step 1: Let a=36. Let us take x as 3, since, 33=27 is the nearest perfect cube which is less than 36.


Step 2: Apply the formula.  ∛36≅ 3((33+2×36) / (2(3)3+36))= 3.3


Hence, 3.3 is the approximate cubic root of 36.

Problem 1

Find (∛32/ ∛36) × (∛33/ ∛36) × (∛34/ ∛36)

Okay, lets begin

 (∛32/ ∛36) × (∛33/ ∛36) × (∛34/ ∛16)


= (∛32× ∛33× ∛34) / (∛36× ∛36× ∛36)


=(∛32× ∛33× ∛34)/ ((36)⅓)3


=(∛32× ∛33× ∛34)/36


=(3.174 × 3.207 × 3.239)/36


Answer: (3.174 × 3.207 × 3.239)/36
 

Explanation

We used the fact that ((36)⅓)3=36 and then found the cube roots of 32,33, and 34 and simplified.

Problem 2

The length, breadth and height of a cuboid is 4 unit, 3 unit, and 3.5cm respectively. Find its volume, also find the measure of a side of a cube whose volume is 36 cubic units.

Okay, lets begin

Volume of a cuboid = length × breadth × height = 4 × 3 × 3.5 cubic units = 42 cubic units.


Given, Volume of a cube = 36 cubic units


⇒ side × side × side = 36 cubic units


⇒ side =  ∛36


⇒ side = 3.301 units


Answer: Volume of the cuboid = 42 cubic units


Side length of the cube = 3.301 units
 

Explanation

Applied the formula and concept of the volume of a cuboid and cube and solved.

Problem 3

Multiply ∛36 × ∛125

Okay, lets begin

∛36×∛125

= 3.301×5

= 16.505


Answer:       16.505
 

Explanation

We know that the cubic root of 125 is 5, hence multiplying  ∛125 with ∛36.
