## How to Calculate the Value of the Cube Root of 238?

### Cube Root of 238 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 = 238

Let us assume x as 6

[∵ 6^{3} = 216 and 216 is the nearest perfect cube that is less than 238]

⇒ x = 6

Therefore,

∛238 = 6 (6^{3} + 2 × 238)/(2 × 6^{3} + 238)) = 6.2

⇒ ∛238 ≈ 6.2

Therefore, the cube root of 238 is 6.2 approximately.

## Is the Cube Root of 238 Irrational?

Yes, because ∛238 = ∛(2 × 7 × 17) and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 238 is an irrational number.

## Cube Root of 238 Solved Examples

**Example 1: What is the value of ∛238 + ∛(-238)?****Solution:**The cube root of -238 is equal to the negative of the cube root of 238.

i.e. ∛-238 = -∛238Therefore, ∛238 + ∛(-238) = ∛238 - ∛238 = 0

**Example 2: Find the real root of the equation x**^{3}− 238 = 0.**Solution:**x

^{3}− 238 = 0 i.e. x^{3}= 238

Solving for x gives us,

x = ∛238, x = ∛238 × (-1 + √3i))/2 and x = ∛238 × (-1 - √3i))/2

where i is called the imaginary unit and is equal to √-1.

Ignoring imaginary roots,

x = ∛238

Therefore, the real root of the equation x^{3}− 238 = 0 is for x = ∛238 = 6.1972.**Example 3: The volume of a spherical ball is 238π in**^{3}. What is the radius of this ball?**Solution:**Volume of the spherical ball = 238π in

^{3}

= 4/3 × π × R^{3}

⇒ R^{3}= 3/4 × 238

⇒ R = ∛(3/4 × 238) = ∛(3/4) × ∛238 = 0.90856 × 6.19715 (∵ ∛(3/4) = 0.90856 and ∛238 = 6.19715)

⇒ R = 5.63048 in^{3}

## FAQs on Cube Root of 238

### What is the Value of the Cube Root of 238?

We can express 238 as 2 × 7 × 17 i.e. ∛238 = ∛(2 × 7 × 17) = 6.19715. Therefore, the value of the cube root of 238 is 6.19715.

### What is the Value of 3 Plus 11 Cube Root 238?

The value of ∛238 is 6.197. So, 3 + 11 × ∛238 = 3 + 11 × 6.197 = 71.167. Hence, the value of 3 plus 11 cube root 238 is 71.167.

### How to Simplify the Cube Root of 238/27?

We know that the cube root of 238 is 6.19715 and the cube root of 27 is 3. Therefore, ∛(238/27) = (∛238)/(∛27) = 6.197/3 = 2.0657.

### Is 238 a Perfect Cube?

The number 238 on prime factorization gives 2 × 7 × 17. Here, the prime factor 2 is not in the power of 3. Therefore the cube root of 238 is irrational, hence 238 is not a perfect cube.

### What is the Cube of the Cube Root of 238?

The cube of the cube root of 238 is the number 238 itself i.e. (∛238)^{3} = (238^{1/3})^{3} = 238.

### What is the Cube Root of -238?

The cube root of -238 is equal to the negative of the cube root of 238. Therefore, ∛-238 = -(∛238) = -(6.197) = -6.197.
