Cube Root of 1728 Solved Examples

Example 1: The volume of a spherical ball is 1728π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 1728π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 1728
⇒ R = ∛(3/4 × 1728) = ∛(3/4) × ∛1728 = 0.90856 × 12 (∵ ∛(3/4) = 0.90856 and ∛1728 = 12)
⇒ R = 10.90272 in^{3} 
Example 2: What is the value of ∛1728 ÷ ∛(1728)?
Solution:
The cube root of 1728 is equal to the negative of the cube root of 1728.
⇒ ∛1728 = ∛1728
Therefore,
⇒ ∛1728/∛(1728) = ∛1728/(∛1728) = 1 
Example 3: Find the real root of the equation x^{3} − 1728 = 0.
Solution:
x^{3} − 1728 = 0 i.e. x^{3} = 1728
Solving for x gives us,
x = ∛1728, x = ∛1728 × (1 + √3i))/2 and x = ∛1728 × (1  √3i))/2
where i is called the imaginary unit and is equal to √1.
Ignoring imaginary roots,
x = ∛1728
Therefore, the real root of the equation x^{3} − 1728 = 0 is for x = ∛1728 = 12.
FAQs on Cube Root of 1728
What is the Value of the Cube Root of 1728?
We can express 1728 as 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3 i.e. ∛1728 = ∛(2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3) = 12. Therefore, the value of the cube root of 1728 is 12.
