How to Calculate the Value of the Cube Root of 270?
Cube Root of 270 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 = 270
Let us assume x as 6
[∵ 6^{3} = 216 and 216 is the nearest perfect cube that is less than 270]
⇒ x = 6
Therefore,
∛270 = 6 (6^{3} + 2 × 270)/(2 × 6^{3} + 270)) = 6.46
⇒ ∛270 ≈ 6.46
Therefore, the cube root of 270 is 6.46 approximately.
Is the Cube Root of 270 Irrational?
Yes, because ∛270 = ∛(2 × 3 × 3 × 3 × 5) = 3 ∛10 and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 270 is an irrational number.

Cube Root of 270 Solved Examples

Example 1: What is the value of ∛270 + ∛(270)?
Solution:
The cube root of 270 is equal to the negative of the cube root of 270.
i.e. ∛270 = ∛270
Therefore, ∛270 + ∛(270) = ∛270  ∛270 = 0 
Example 2: The volume of a spherical ball is 270π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 270π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 270
⇒ R = ∛(3/4 × 270) = ∛(3/4) × ∛270 = 0.90856 × 6.4633 (∵ ∛(3/4) = 0.90856 and ∛270 = 6.4633)
⇒ R = 5.8723 in^{3} 
Example 3: Find the real root of the equation x^{3} − 270 = 0.
Solution:
x^{3} − 270 = 0 i.e. x^{3} = 270
Solving for x gives us,
x = ∛270, x = ∛270 × (1 + √3i))/2 and x = ∛270 × (1  √3i))/2
where i is called the imaginary unit and is equal to √1.
Ignoring imaginary roots,
x = ∛270
Therefore, the real root of the equation x^{3} − 270 = 0 is for x = ∛270 = 6.4633.
FAQs on Cube Root of 270
What is the Value of the Cube Root of 270?
We can express 270 as 2 × 3 × 3 × 3 × 5 i.e. ∛270 = ∛(2 × 3 × 3 × 3 × 5) = 6.4633. Therefore, the value of the cube root of 270 is 6.4633.
If the Cube Root of 270 is 6.46, Find the Value of ∛0.27.
Let us represent ∛0.27 in p/q form i.e. ∛(270/1000) = 6.46/10 = 0.65. Hence, the value of ∛0.27 = 0.65.
What is the Cube Root of 270?
The cube root of 270 is equal to the negative of the cube root of 270. Therefore, ∛270 = (∛270) = (6.463) = 6.463.
How to Simplify the Cube Root of 270/216?
We know that the cube root of 270 is 6.4633 and the cube root of 216 is 6. Therefore, ∛(270/216) = (∛270)/(∛216) = 6.463/6 = 1.0772.
Is 270 a Perfect Cube?
The number 270 on prime factorization gives 2 × 3 × 3 × 3 × 5. Here, the prime factor 2 is not in the power of 3. Therefore the cube root of 270 is irrational, hence 270 is not a perfect cube.
Why is the Value of the Cube Root of 270 Irrational?
The value of the cube root of 270 cannot be expressed in the form of p/q where q ≠ 0. Therefore, the number ∛270 is irrational.
