How to Calculate the Value of the Cube Root of 99?
Cube Root of 99 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 = 99
Let us assume x as 4
[∵ 4^{3} = 64 and 64 is the nearest perfect cube that is less than 99]
⇒ x = 4
Therefore,
∛99 = 4 (4^{3} + 2 × 99)/(2 × 4^{3} + 99)) = 4.62
⇒ ∛99 ≈ 4.62
Therefore, the cube root of 99 is 4.62 approximately.
Is the Cube Root of 99 Irrational?
Yes, because ∛99 = ∛(3 × 3 × 11) and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 99 is an irrational number.

Cube Root of 99 Solved Examples

Example 1: Given the volume of a cube is 99 in^{3}. Find the length of the side of the cube.
Solution:
Volume of the Cube = 99 in^{3} = a^{3}
⇒ a^{3} = 99
Cube rooting on both sides,
⇒ a = ∛99 in
Since the cube root of 99 is 4.63, therefore, the length of the side of the cube is 4.63 in. 
Example 2: What is the value of ∛99 + ∛(99)?
Solution:
The cube root of 99 is equal to the negative of the cube root of 99.
i.e. ∛99 = ∛99
Therefore, ∛99 + ∛(99) = ∛99  ∛99 = 0

Example 3: The volume of a spherical ball is 99π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 99π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 99
⇒ R = ∛(3/4 × 99) = ∛(3/4) × ∛99 = 0.90856 × 4.62607 (∵ ∛(3/4) = 0.90856 and ∛99 = 4.62607)
⇒ R = 4.20306 in^{3}
FAQs on Cube Root of 99
What is the Value of the Cube Root of 99?
We can express 99 as 3 × 3 × 11 i.e. ∛99 = ∛(3 × 3 × 11) = 4.62607. Therefore, the value of the cube root of 99 is 4.62607.
What is the Cube Root of 99?
The cube root of 99 is equal to the negative of the cube root of 99. Therefore, ∛99 = (∛99) = (4.626) = 4.626.
What is the Cube of the Cube Root of 99?
The cube of the cube root of 99 is the number 99 itself i.e. (∛99)^{3} = (99^{1/3})^{3} = 99.
Is 99 a Perfect Cube?
The number 99 on prime factorization gives 3 × 3 × 11. Here, the prime factor 3 is not in the power of 3. Therefore the cube root of 99 is irrational, hence 99 is not a perfect cube.
Why is the Value of the Cube Root of 99 Irrational?
The value of the cube root of 99 cannot be expressed in the form of p/q where q ≠ 0. Therefore, the number ∛99 is irrational.
If the Cube Root of 99 is 4.63, Find the Value of ∛0.099.
Let us represent ∛0.099 in p/q form i.e. ∛(99/1000) = 4.63/10 = 0.46. Hence, the value of ∛0.099 = 0.46.
