Cube Root of 1000
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 1000 and explain the methods used.
What is the Cube Root of 1000?
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, ∛1000 is written as 1000(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 1000, then y3 can be 1000. Since 1000 is a perfect cube, its cube root is exactly 10.
Finding the Cube Root of 1000
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 1000. The common methods we follow to find the cube root are given below:
- Prime factorization method
- Approximation method
- Subtraction method
- Halley’s method
Since 1000 is a perfect cube, we can use the prime factorization method for simplicity.
Cube Root of 1000 by Prime Factorization
Let's find the cube root of 1000 using the prime factorization method.
First, factor 1000 into its prime factors: 1000 = 2 × 2 × 2 × 5 × 5 × 5
Grouping the factors in triples gives us: (2 × 2 × 2) × (5 × 5 × 5)
Each group represents a cube, so take one factor from each group:
∛1000 = 2 × 5 = 10
The cube root of 1000 is 10.
Common Mistakes and How to Avoid Them in Finding the Cube Root of 1000
Finding the cube root 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 approximate cube roots for perfect cube numbers.
Children sometimes try to calculate an approximate value for the cube root of numbers like 1000, which are perfect cubes. To avoid this error, recognize that numbers like 1000 have exact cube roots, in this case, 10.
Cube Root of 1000 Examples:
Problem 1
Imagine you have a cube-shaped toy that has a total volume of 1000 cubic centimeters. Find the length of one side of the cube.
Side of the cube = ∛1000 = 10 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 exactly 10 units.
Problem 2
A company manufactures 1000 cubic meters of material. Calculate the amount of material left after using 200 cubic meters.
The amount of material left is 800 cubic meters.
Explanation
To find the remaining material, we need to subtract the used material from the total amount:
1000 - 200 = 800 cubic meters.
Problem 3
A bottle holds 1000 cubic meters of volume. Another bottle holds a volume of 300 cubic meters. What would be the total volume if the bottles are combined?
The total volume of the combined bottles is 1300 cubic meters.
Explanation
Let’s add the volume of both bottles:
1000 + 300 = 1300 cubic meters.
Problem 4
When the cube root of 1000 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?
2 × 10 = 20 The cube of 20 = 8000
Explanation
When we multiply the cube root of 1000 by 2, it results in a significant increase in the volume because the cube increases exponentially.
Problem 5
Find ∛(500+500).
∛(500+500) = ∛1000 = 10
Explanation
As shown in the question ∛(500+500), we can simplify that by adding them.
So, 500 + 500 = 1000.
Then we use this step: ∛1000 = 10 to get the answer.

Important Glossaries for Cube Root of 1000
- 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: 10 × 10 × 10 = 1000, therefore, 1000 is a perfect cube.
- Exponent: The exponent form of the number denotes the number of times a number can be multiplied by itself. In 1000(1/3), ⅓ is the exponent which denotes the cube root of 1000.
- Radical sign: The symbol that is used to represent a root which is expressed as (∛).
- Rational number: A number that can be expressed as a fraction of two integers. The cube root of 1000 is rational because it is 10, which can be expressed as 10/1.
