What is the Cube Root of 216?
The cube root of 216 is the number which when multiplied by itself three times gives the product as 216. Since 216 can be expressed as 2 × 2 × 2 × 3 × 3 × 3. Therefore, the cube root of 216 = ∛(2 × 2 × 2 × 3 × 3 × 3) = 6.
How to Calculate the Value of the Cube Root of 216?
Cube Root of 216 by Prime Factorization
 Prime factorization of 216 is 2 × 2 × 2 × 3 × 3 × 3
 Simplifying the above expression: 2^{3} × 3^{3}
 Simplifying further: 6^{3}
Therefore, the cube root of 216 by prime factorization is (2 × 2 × 2 × 3 × 3 × 3)^{1/3} = 6.
Is the Cube Root of 216 Irrational?
No, because ∛216 = ∛(2 × 2 × 2 × 3 × 3 × 3) can be expressed in the form of p/q i.e. 6/1. Therefore, the value of the cube root of 216 is an integer (rational).

Cube Root of 216 Solved Examples

Example 1: Find the real root of the equation x^{3} − 216 = 0.
Solution:
x^{3} − 216 = 0 i.e. x^{3} = 216
Solving for x gives us,
x = ∛216, x = ∛216 × (1 + √3i))/2 and x = ∛216 × (1  √3i))/2
where i is called the imaginary unit and is equal to √1.
Ignoring imaginary roots,
x = ∛216
Therefore, the real root of the equation x^{3} − 216 = 0 is for x = ∛216 = 6. 
Example 2: Given the volume of a cube is 216 in^{3}. Find the length of the side of the cube.
Solution:
Volume of the Cube = 216 in^{3} = a^{3}
⇒ a^{3} = 216
Cube rooting on both sides,
⇒ a = ∛216 in
Since the cube root of 216 is 6, therefore, the length of the side of the cube is 6 in. 
Example 3: What is the value of ∛216 + ∛(216)?
Solution:
The cube root of 216 is equal to the negative of the cube root of 216.
i.e. ∛216 = ∛216
Therefore, ∛216 + ∛(216) = ∛216  ∛216 = 0
FAQs on Cube Root of 216
What is the Value of the Cube Root of 216?
We can express 216 as 2 × 2 × 2 × 3 × 3 × 3 i.e. ∛216 = ∛(2 × 2 × 2 × 3 × 3 × 3) = 6. Therefore, the value of the cube root of 216 is 6.
How to Simplify the Cube Root of 216/343?
We know that the cube root of 216 is 6 and the cube root of 343 is 7. Therefore, ∛(216/343) = (∛216)/(∛343) = 6/7 = 0.8571.
What is the Cube of the Cube Root of 216?
The cube of the cube root of 216 is the number 216 itself i.e. (∛216)^{3} = (216^{1/3})^{3} = 216.
What is the Cube Root of 216?
The cube root of 216 is equal to the negative of the cube root of 216. Therefore, ∛216 = (∛216) = (6) = 6.
Why is the value of the Cube Root of 216 Rational?
