Cube Root of 795
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 795 and explain the methods used.
What is the Cube Root of 795?
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, ∛795 is written as 795^(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 795, then y^3 can be 795. Since the cube root of 795 is not an exact value, we can write it as approximately 9.283.
Finding the Cube Root of 795
Finding the cube root of a number involves identifying the number that must be multiplied three times to result in the target number. Now, we will go through the different ways to find the cube root of 795. 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 795 is not a perfect cube, we use Halley’s method.
Cube Root of 795 by Halley’s method
Let's find the cube root of 795 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 = 795; x = 9 ∛a ≅ 9((9^3 + 2 × 795) / (2 × 9^3 + 795)) ∛795 ≅ 9((729 + 2 × 795) / (2 × 729 + 795)) ∛795 ≅ 9.283 The cube root of 795 is approximately 9.283.
Common Mistakes and How to Avoid Them in the Cube Root of 795
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 students commonly make and ways to avoid them:
Mistake 1
Trying to find perfect cube roots for non-perfect cube numbers.
Children often try to calculate an exact whole number for the cube root of numbers like 795, which are not perfect cubes. For example, they might assume they would get an exact whole number for 795 like they get for 512 (since 8 × 8 × 8 = 512). To avoid this error, memorize that some numbers don't have a perfect cube root, meaning the cube root of 795 is approximately 9.283.
Mistake 2
Ignoring the exponent form
Most of us might forget that the cube root can also be written in exponent form. For example, forgetting that the cube root of 795 is 795^(1/3). To avoid this error, always learn the forms in which we can express the cube root of a number.
Mistake 3
Confusing cube root with division
Assuming the cube root of 795 is to divide 795 by 3. For example, mistakenly assume 795/3. To avoid this, children should remember that the cube root of 795 is the number they multiply by itself three times to get 795.
Mistake 4
Using prime factorization instead of Halley’s method
Instead of using Halley’s method for non-perfect cubes, children end up using prime factorization. For example, they might try to find the cube root of 795 by breaking it down into its prime factors. Remember that prime factorization can help analyze a number's factors, but it's not the best method for non-perfect cubes. Since 795 is a non-perfect cube, you can use either the approximation method or Halley’s method.
Mistake 5
Rounding too early
Rounding the cube root too early in the process can lead to errors in the subsequent steps. For example, we might round the cube root of 795 to 9.3 too early in the calculation. To avoid this, ensure the whole calculation is done, then round the final result.
Cube Root of 795 Examples:
Problem 1
Imagine you have a cube-shaped container that has a total volume of 795 cubic centimeters. Find the length of one side of the container equal to its cube root.
Side of the cube = ∛795 = 9.28 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 9.28 units.
Problem 2
A company manufactures 795 cubic meters of material. Calculate the amount of material left after using 200 cubic meters.
The amount of material left is 595 cubic meters.
Explanation
To find the remaining material, we need to subtract the used material from the total amount: 795 - 200 = 595 cubic meters.
Problem 3
A tank holds 795 cubic meters of water. Another tank holds a volume of 150 cubic meters. What would be the total volume if the tanks are combined?
The total volume of the combined tanks is 945 cubic meters.
Explanation
Let’s add the volume of both tanks: 795 + 150 = 945 cubic meters.
Problem 4
When the cube root of 795 is multiplied by 3, calculate the resultant value. How will this affect the cube of the new value?
3 × 9.28 = 27.84 The cube of 27.84 = 21,545.47
Explanation
When we multiply the cube root of 795 by 3, it results in a significant increase in the volume because the cube increases exponentially.
Problem 5
Find ∛(500 + 295).
∛(500 + 295) = ∛795 ≈ 9.283
Explanation
As shown in the question ∛(500 + 295), we can simplify that by adding them. So, 500 + 295 = 795. Then we use this step: ∛795 ≈ 9.283 to get the answer.

Important Glossaries for Cube Root of 795
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 795^(1/3), ⅓ is the exponent which denotes the cube root of 795. Radical sign: The symbol that is used to represent a root is expressed as (∛). Irrational number: Numbers that cannot be expressed as a simple fraction. The cube root of 795 is irrational because its decimal form continues without repeating.
