How to Calculate the Value of the Cube Root of 36?
Cube Root of 36 by Halley’s Method
Its formula is ∛a ≈ x ((x3 + 2a)/(2×3 + a))
where,
a = number whose cube root is being calculated
x = integer guess of its cube root.
Here a = 36
Let us assume x as 3
[∵ 33 = 27 and 27 is the nearest perfect cube that is less than 36]
⇒ x = 3
Therefore,
∛36 = 3 (33 + 2 × 36)/(2 × 33 + 36)) = 3.3
⇒ ∛36 ≈ 3.3
Therefore, the cube root of 36 is 3.3 approximately.
Is the Cube Root of 36 Irrational?
Yes, because ∛36 = ∛(2 × 2 × 3 × 3) and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 36 is an irrational number.

Cube Root of 36 Solved Examples

Example 1: Given the volume of a cube is 36 in3. Find the length of the side of the cube.
Solution:
Volume of the Cube = 36 in3 = a3
⇒ a3 = 36
Cube rooting on both sides,
⇒ a = ∛36 in
Since the cube root of 36 is 3.3, therefore, the length of the side of the cube is 3.3 in. 
Example 2: What is the value of ∛36 ÷ ∛(36)?
Solution:
The cube root of 36 is equal to the negative of the cube root of 36.
⇒ ∛36 = ∛36
Therefore,
⇒ ∛36/∛(36) = ∛36/(∛36) = 1 
Example 3: Find the real root of the equation x3 − 36 = 0.
Solution:
x3 − 36 = 0 i.e. x3 = 36
Solving for x gives us,
x = ∛36, x = ∛36 × (1 + √3i))/2 and x = ∛36 × (1 – √3i))/2
where i is called the imaginary unit and is equal to √1.
Ignoring imaginary roots,
x = ∛36
Therefore, the real root of the equation x3 − 36 = 0 is for x = ∛36 = 3.3019.
FAQs on Cube Root of 36
What is the Value of the Cube Root of 36?
We can express 36 as 2 × 2 × 3 × 3 i.e. ∛36 = ∛(2 × 2 × 3 × 3) = 3.30193. Therefore, the value of the cube root of 36 is 3.30193.
Is 36 a Perfect Cube?
The number 36 on prime factorization gives 2 × 2 × 3 × 3. Here, the prime factor 2 is not in the power of 3. Therefore the cube root of 36 is irrational, hence 36 is not a perfect cube.
If the Cube Root of 36 is 3.3, Find the Value of ∛0.036.
Let us represent ∛0.036 in p/q form i.e. ∛(36/1000) = 3.3/10 = 0.33. Hence, the value of ∛0.036 = 0.33.
What is the Cube of the Cube Root of 36?
The cube of the cube root of 36 is the number 36 itself i.e. (∛36)3 = (361/3)3 = 36.
Why is the Value of the Cube Root of 36 Irrational?
The value of the cube root of 36 cannot be expressed in the form of p/q where q ≠ 0. Therefore, the number ∛36 is irrational.
What is the Cube Root of 36?
The cube root of 36 is equal to the negative of the cube root of 36. Therefore, ∛36 = (∛36) = (3.302) = 3.302.
