Cube Root of 229
A number we multiply by itself three times to get the original number is its cube root. It has various uses in real life, such as finding the volume of cube-shaped objects and designing structures. We will now find the cube root of 229 and explain the methods used.
What is the Cube Root of 229?
We have learned the definition of the cube root. Now, let’s learn how it is represented using a symbol and exponent. The symbol we use to express the cube root is the radical sign (∛), and the exponent we use is ⅓.
In exponential form, ∛229 is written as 229^(1/3). The cube root is just the opposite operation of finding the cube of a number.
For example, assume ‘y’ as the cube root of 229, then y^3 can be 229. Since the cube root of 229 is not an exact value, we can write it as approximately 6.135.
Finding the Cube Root of 229
Finding the cube root of a number is to identify the number that must be multiplied three times resulting in the target number. Now, we will go through the different ways to find the cube root of 229. The common methods we follow to find the cube root are given below:
- Prime factorization method
- Approximation method
- Subtraction method
- Halley’s method
To find the cube root of a non-perfect number, we often follow Halley’s method. Since 229 is not a perfect cube, we use Halley’s method.
Cube Root of 229 by Halley’s method
Let's find the cube root of 229 using Halley’s method.
The formula is ∛a ≅ x((x^3 + 2a) / (2x^3 + a))
where: a = the number for which the cube root is being calculated
x = the nearest perfect cube Substituting,
a = 229;
x = 6
∛a ≅ 6((6^3 + 2 × 229) / (2 × 6^3 + 229))
∛229 ≅ 6((216 + 2 × 229) / (2 × 216 + 229))
∛229 ≅ 6.135
The cube root of 229 is approximately 6.135.
Common Mistakes and How to Avoid Them in the Cube Root of 229
Finding the perfect cube of a number without any errors can be a difficult task for students. This happens for many reasons. Here are a few mistakes the students commonly make and the ways to avoid them:
Mistake 1
Trying to find perfect cube roots for non-perfect cube numbers.
Children always try to calculate an exact whole number for the cube root of numbers like 229, which are not perfect cubes.
For example, they assume that they would get an exact whole number for 229 just like they get for 216 (since ∛216 = 6). To avoid this error, memorize that some numbers don't have a perfect cube root, that is, the cube root of 229 is approximately 6.135.
Cube Root of 229 Examples:
Problem 1
Imagine you have a cube-shaped toy that has a total volume of 229 cubic centimeters. Find the length of one side of the box equal to its cube root.
Side of the cube = ∛229 ≈ 6.135 units
Explanation
To find the side of the cube, we need to find the cube root of the given volume. Therefore, the side length of the cube is approximately 6.135 units.
Problem 2
A company manufactures 229 cubic meters of material. Calculate the amount of material left after using 30 cubic meters.
The amount of material left is 199 cubic meters.
Explanation
To find the remaining material, we need to subtract the used material from the total amount: 229 - 30 = 199 cubic meters.
Problem 3
A bottle holds 229 cubic meters of volume. Another bottle holds a volume of 50 cubic meters. What would be the total volume if the bottles are combined?
The total volume of the combined bottles is 279 cubic meters.
Explanation
Let’s add the volume of both bottles: 229 + 50 = 279 cubic meters.
Problem 4
When the cube root of 229 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?
2 × 6.135 = 12.27 The cube of 12.27 = 1845.69
Explanation
When we multiply the cube root of 229 by 2, it results in a significant increase in the volume because the cube increases exponentially.
Problem 5
Find ∛(115 + 114).
∛(115 + 114) = ∛229 ≈ 6.135
Explanation
As shown in the question ∛(115 + 114), we can simplify that by adding them. So, 115 + 114 = 229. Then we use this step: ∛229 ≈ 6.135 to get the answer.

Important Glossaries for Cube Root of 229
- Cube root: The number that is multiplied three times by itself to get the given number is the cube root of that number.
- Perfect cube: A number is a perfect cube when it is the product of multiplying a number three times by itself. A perfect cube always results in a whole number. For example, 2 × 2 × 2 = 8, therefore, 8 is a perfect cube.
- Exponent: The exponent form of the number denotes the number of times a number can be multiplied by itself. In 229^(1/3), ⅓ is the exponent which denotes the cube root of 229.
- Radical sign: The symbol that is used to represent a root is expressed as (∛).
- Irrational number: The numbers that cannot be put in fractional forms are irrational. For example, the cube root of 229 is irrational because its decimal form goes on continuously without repeating the numbers.
