How to Calculate the Value of the Cube Root of 162?
Cube Root of 162 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 = 162
Let us assume x as 5
[∵ 5^{3} = 125 and 125 is the nearest perfect cube that is less than 162]
⇒ x = 5
Therefore,
∛162 = 5 (5^{3} + 2 × 162)/(2 × 5^{3} + 162)) = 5.45
⇒ ∛162 ≈ 5.45
Therefore, the cube root of 162 is 5.45 approximately.
Is the Cube Root of 162 Irrational?
Yes, because ∛162 = ∛(2 × 3 × 3 × 3 × 3) = 3 ∛6 and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 162 is an irrational number.

Cube Root of 162 Solved Examples

Example 1: What is the value of ∛162 + ∛(162)?
Solution:
The cube root of 162 is equal to the negative of the cube root of 162.
i.e. ∛162 = ∛162
Therefore, ∛162 + ∛(162) = ∛162  ∛162 = 0

Example 2: Find the real root of the equation x^{3} − 162 = 0.
Solution:
x^{3} − 162 = 0 i.e. x^{3} = 162
Solving for x gives us,
x = ∛162, x = ∛162 × (1 + √3i))/2 and x = ∛162 × (1  √3i))/2
where i is called the imaginary unit and is equal to √1.
Ignoring imaginary roots,
x = ∛162
Therefore, the real root of the equation x^{3} − 162 = 0 is for x = ∛162 = 5.4514.

Example 3: The volume of a spherical ball is 162π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 162π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 162
⇒ R = ∛(3/4 × 162) = ∛(3/4) × ∛162 = 0.90856 × 5.45136 (∵ ∛(3/4) = 0.90856 and ∛162 = 5.45136)
⇒ R = 4.95289 in^{3}
FAQs on Cube Root of 162
What is the Value of the Cube Root of 162?
We can express 162 as 2 × 3 × 3 × 3 × 3 i.e. ∛162 = ∛(2 × 3 × 3 × 3 × 3) = 5.45136. Therefore, the value of the cube root of 162 is 5.45136.
What is the Cube Root of 162?
The cube root of 162 is equal to the negative of the cube root of 162. Therefore, ∛162 = (∛162) = (5.451) = 5.451.
How to Simplify the Cube Root of 162/343?
We know that the cube root of 162 is 5.45136 and the cube root of 343 is 7. Therefore, ∛(162/343) = (∛162)/(∛343) = 5.451/7 = 0.7787.
If the Cube Root of 162 is 5.45, Find the Value of ∛0.162.
Let us represent ∛0.162 in p/q form i.e. ∛(162/1000) = 5.45/10 = 0.55. Hence, the value of ∛0.162 = 0.55.
What is the Value of 19 Plus 13 Cube Root 162?
The value of ∛162 is 5.451. So, 19 + 13 × ∛162 = 19 + 13 × 5.451 = 89.863. Hence, the value of 19 plus 13 cube root 162 is 89.863.
Why is the Value of the Cube Root of 162 Irrational?
The value of the cube root of 162 cannot be expressed in the form of p/q where q ≠ 0. Therefore, the number ∛162 is irrational.
