Cube Root of 512 Solved Examples

Example 1: The volume of a spherical ball is 512π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 512π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 512
⇒ R = ∛(3/4 × 512) = ∛(3/4) × ∛512 = 0.90856 × 8 (∵ ∛(3/4) = 0.90856 and ∛512 = 8)
⇒ R = 7.26848 in^{3} 
Example 2: Given the volume of a cube is 512 in^{3}. Find the length of the side of the cube.
Solution:
Volume of the Cube = 512 in^{3} = a^{3}
⇒ a^{3} = 512
Cube rooting on both sides,
⇒ a = ∛512 in
Since the cube root of 512 is 8, therefore, the length of the side of the cube is 8 in. 
Example 3: Find the real root of the equation x^{3} − 512 = 0.
Solution:
x^{3} − 512 = 0 i.e. x^{3} = 512
Solving for x gives us,
x = ∛512, x = ∛512 × (1 + √3i))/2 and x = ∛512 × (1  √3i))/2
where i is called the imaginary unit and is equal to √1.
Ignoring imaginary roots,
x = ∛512
Therefore, the real root of the equation x^{3} − 512 = 0 is for x = ∛512 = 8.
