What is the Cube Root of 27?
The cube root of 27 is the number which when multiplied by itself three times gives the product as 27. Since 27 can be expressed as 3 × 3 × 3. Therefore, the cube root of 27 = ∛(3 × 3 × 3) = 3.
How to Calculate the Value of the Cube Root of 27?
Cube Root of 27 by Prime Factorization
 Prime factorization of 27 is 3 × 3 × 3
 Simplifying the above expression: 3^{3}
Therefore, the cube root of 27 by prime factorization is (3 × 3 × 3)^{1/3} = 3.
Is the Cube Root of 27 Irrational?
No, because ∛27 = ∛(3 × 3 × 3) can be expressed in the form of p/q i.e. 3/1. Therefore, the value of the cube root of 27 is an integer (rational).

Cube Root of 27 Solved Examples

Example 1: What is the value of ∛27 + ∛(27)?
Solution:
The cube root of 27 is equal to the negative of the cube root of 27.
i.e. ∛27 = ∛27
Therefore, ∛27 + ∛(27) = ∛27  ∛27 = 0 
Example 2: The volume of a spherical ball is 27π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 27π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 27
⇒ R = ∛(3/4 × 27) = ∛(3/4) × ∛27 = 0.90856 × 3 (∵ ∛(3/4) = 0.90856 and ∛27 = 3)
⇒ R = 2.72568 in^{3} 
Example 3: Given the volume of a cube is 27 in^{3}. Find the length of the side of the cube.
Solution:
Volume of the Cube = 27 in^{3} = a^{3}
⇒ a^{3} = 27
Cube rooting on both sides,
⇒ a = ∛27 in
Since the cube root of 27 is 3, therefore, the length of the side of the cube is 3 in.
FAQs on Cube Root of 27
