Cube Root of 941
A number that, when multiplied by itself three times, gives the original number is its cube root. It has various applications in real life, such as determining the dimensions of cube-shaped objects and engineering structures. We will now find the cube root of 941 and explain the methods used.
What is the Cube Root of 941?
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 is ⅓.
In exponential form, ∛941 is written as 941(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 941, then y3 can be 941. Since the cube root of 941 is not an exact value, we can write it as approximately 9.791.
Finding the Cube Root of 941
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 941. 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 cube number, we often follow Halley’s method. Since 941 is not a perfect cube, we use Halley’s method.
Cube Root of 941 by Halley’s Method
Let's find the cube root of 941 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 = 941;
x = 10
∛a ≅ 10((103 + 2 × 941) / (2 × 103 + 941))
∛941 ≅ 10((1000 + 1882) / (2000 + 941))
∛941 ≅ 9.791
The cube root of 941 is approximately 9.791.
Common Mistakes and How to Avoid Them in the Cube Root of 941
Finding the cube root without errors can be challenging. Here are some common mistakes and how to avoid them:
Mistake 1
Trying to find perfect cube roots for non-perfect cube numbers.
Students often try to find an exact whole number for the cube root of numbers like 941, which are not perfect cubes.
For example, they might expect a whole number result like with 1000 (since ∛1000 = 10). To avoid this error, remember that some numbers don't have a perfect cube root; for example, the cube root of 941 is approximately 9.791.
Cube Root of 941 Examples:
Problem 1
Imagine you have a cube-shaped box with a total volume of 941 cubic centimeters. Find the length of one side of the box.
Side of the cube = ∛941 ≈ 9.791 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 9.791 units.
Problem 2
A company manufactures 941 cubic meters of material. Calculate the amount of material left after using 300 cubic meters.
The amount of material left is 641 cubic meters.
Explanation
To find the remaining material, subtract the used material from the total amount:
941 - 300 = 641 cubic meters.
Problem 3
A container holds 941 cubic meters of liquid. Another container holds 50 cubic meters. What would be the total volume if the containers are combined?
The total volume of the combined containers is 991 cubic meters.
Explanation
Add the volume of both containers:
941 + 50 = 991 cubic meters.
Problem 4
When the cube root of 941 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?
2 × 9.791 ≈ 19.582
The cube of 19.582 is approximately 7498.97
Explanation
When we multiply the cube root of 941 by 2, it results in a significant increase in volume because the cube increases exponentially.
Problem 5
Find ∛(900 + 41).
∛(900 + 41) = ∛941 ≈ 9.791
Explanation
As shown in the question ∛(900 + 41), simplify by adding them.
So, 900 + 41 = 941.
Then, use this step: ∛941 ≈ 9.791 to get the answer.

Important Glossaries for Cube Root of 941
- 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 941(1/3), ⅓ is the exponent which denotes the cube root of 941.
- Radical sign: The symbol that is used to represent a root is expressed as (∛).
- Irrational number: Numbers that cannot be put in fractional form are irrational. For example, the cube root of 941 is irrational because its decimal form goes on continuously without repeating the numbers.
