How to Calculate the Value of the Cube Root of 800?
Cube Root of 800 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 = 800
Let us assume x as 9
[∵ 9^{3} = 729 and 729 is the nearest perfect cube that is less than 800]
⇒ x = 9
Therefore,
∛800 = 9 (9^{3} + 2 × 800)/(2 × 9^{3} + 800)) = 9.28
⇒ ∛800 ≈ 9.28
Therefore, the cube root of 800 is 9.28 approximately.
Is the Cube Root of 800 Irrational?
Yes, because ∛800 = ∛(2 × 2 × 2 × 2 × 2 × 5 × 5) = 2 ∛100 and it cannot be expressed in the form of p/q where q ≠ 0. Therefore, the value of the cube root of 800 is an irrational number.

Cube Root of 800 Solved Examples

Example 1: The volume of a spherical ball is 800π in^{3}. What is the radius of this ball?
Solution:
Volume of the spherical ball = 800π in^{3}
= 4/3 × π × R^{3}
⇒ R^{3} = 3/4 × 800
⇒ R = ∛(3/4 × 800) = ∛(3/4) × ∛800 = 0.90856 × 9.28318 (∵ ∛(3/4) = 0.90856 and ∛800 = 9.28318)
⇒ R = 8.43433 in^{3} 
Example 2: Find the real root of the equation x^{3} − 800 = 0.
Solution:
x^{3} − 800 = 0 i.e. x^{3} = 800
Solving for x gives us,
x = ∛800, x = ∛800 × (1 + √3i))/2 and x = ∛800 × (1  √3i))/2
where i is called the imaginary unit and is equal to √1.
Ignoring imaginary roots,
x = ∛800
Therefore, the real root of the equation x^{3} − 800 = 0 is for x = ∛800 = 9.2832.

Example 3: Given the volume of a cube is 800 in^{3}. Find the length of the side of the cube.
Solution:
Volume of the Cube = 800 in^{3} = a^{3}
⇒ a^{3} = 800
Cube rooting on both sides,
⇒ a = ∛800 in
Since the cube root of 800 is 9.28, therefore, the length of the side of the cube is 9.28 in.
FAQs on Cube Root of 800
What is the Value of the Cube Root of 800?
We can express 800 as 2 × 2 × 2 × 2 × 2 × 5 × 5 i.e. ∛800 = ∛(2 × 2 × 2 × 2 × 2 × 5 × 5) = 9.28318. Therefore, the value of the cube root of 800 is 9.28318.
What is the Value of 4 Plus 4 Cube Root 800?
The value of ∛800 is 9.283. So, 4 + 4 × ∛800 = 4 + 4 × 9.283 = 41.132. Hence, the value of 4 plus 4 cube root 800 is 41.132.
What is the Cube Root of 800?
The cube root of 800 is equal to the negative of the cube root of 800. Therefore, ∛800 = (∛800) = (9.283) = 9.283.
If the Cube Root of 800 is 9.28, Find the Value of ∛0.8.
Let us represent ∛0.8 in p/q form i.e. ∛(800/1000) = 9.28/10 = 0.93. Hence, the value of ∛0.8 = 0.93.
What is the Cube of the Cube Root of 800?
The cube of the cube root of 800 is the number 800 itself i.e. (∛800)^{3} = (800^{1/3})^{3} = 800.
Why is the Value of the Cube Root of 800 Irrational?
The value of the cube root of 800 cannot be expressed in the form of p/q where q ≠ 0. Therefore, the number ∛800 is irrational.
