How to Calculate the Value of the Cube Root of 30?
Cube Root of 30 by Halley's Method
Its formula is ∛a ≈ x ((x^{3} + 2a)/(2x^{3} + a))
where,
a = number whose cube root is being calculated
x = integer guess of its cube root.
Here a = 30
Let us assume x as 3
[∵ 3^{3} = 27 and 27 is the nearest perfect cube that is less than 30]
⇒ x = 3
Therefore,
∛30 = 3 (3^{3} + 2 × 30)/(2 × 3^{3} + 30)) = 3.11
⇒ ∛30 ≈ 3.11
Therefore, the cube root of 30 is 3.11 approximately.
Is the Cube Root of 30 Irrational?
Yes, because ∛30 = ∛(2 × 3 × 5) and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 30 is an irrational number.

Cube Root of 30 Solved Examples

Example 1: Given the volume of a cube is 30 in^{3}. Find the length of the side of the cube.
Solution:
Volume of the Cube = 30 in^{3} = a^{3}
⇒ a^{3} = 30
Cube rooting on both sides,
⇒ a = ∛30 in
Since the cube root of 30 is 3.11, therefore, the length of the side of the cube is 3.11 in. 
Example 2: What is the value of ∛30 + ∛(30)?
Solution:
The cube root of 30 is equal to the negative of the cube root of 30.
i.e. ∛30 = ∛30
Therefore, ∛30 + ∛(30) = ∛30  ∛30 = 0

Example 3: The volume of a spherical ball is 30π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 30π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 30
⇒ R = ∛(3/4 × 30) = ∛(3/4) × ∛30 = 0.90856 × 3.10723 (∵ ∛(3/4) = 0.90856 and ∛30 = 3.10723)
⇒ R = 2.8231 in^{3}
FAQs on Cube Root of 30
What is the Value of the Cube Root of 30?
We can express 30 as 2 × 3 × 5 i.e. ∛30 = ∛(2 × 3 × 5) = 3.10723. Therefore, the value of the cube root of 30 is 3.10723.
What is the Cube of the Cube Root of 30?
The cube of the cube root of 30 is the number 30 itself i.e. (∛30)^{3} = (30^{1/3})^{3} = 30.
What is the Value of 16 Plus 3 Cube Root 30?
The value of ∛30 is 3.107. So, 16 + 3 × ∛30 = 16 + 3 × 3.107 = 25.321. Hence, the value of 16 plus 3 cube root 30 is 25.321.
Is 30 a Perfect Cube?
The number 30 on prime factorization gives 2 × 3 × 5. Here, the prime factor 2 is not in the power of 3. Therefore the cube root of 30 is irrational, hence 30 is not a perfect cube.
How to Simplify the Cube Root of 30/8?
We know that the cube root of 30 is 3.10723 and the cube root of 8 is 2. Therefore, ∛(30/8) = (∛30)/(∛8) = 3.107/2 = 1.5535.
If the Cube Root of 30 is 3.11, Find the Value of ∛0.03.
Let us represent ∛0.03 in p/q form i.e. ∛(30/1000) = 3.11/10 = 0.31. Hence, the value of ∛0.03 = 0.31.
