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 274.625 and explain the methods used.

What is the Cube Root of 274.625?

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, ∛274.625 is written as 274.625^(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 274.625, then y^3 can be 274.625. Since the cube root of 274.625 is not an exact integer, we can write it as approximately 6.5.

Finding the Cube Root of 274.625

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 274.625. 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 274.625 is not a perfect cube, we use Halley’s method.

Cube Root of 274.625 by Halley’s method

Let's find the cube root of 274.625 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 = 274.625;

x = 6

∛a ≅ 6((6^3 + 2 × 274.625) / (2 × 6^3 + 274.625))

∛274.625 ≅ 6((216 + 2 × 274.625) / (2 × 216 + 274.625))

∛274.625 ≅ 6.5

The cube root of 274.625 is approximately 6.5.

Common Mistakes and How to Avoid Them in the Cube Root of 274.625

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 the ways to avoid them:

Problem 1

Imagine you have a cube-shaped toy that has a total volume of 274.625 cubic centimeters. Find the length of one side of the cube equal to its cube root.

Okay, lets begin

Side of the cube = ∛274.625 = 6.5 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 6.5 units.

Well explained 👍

Problem 2

A company manufactures 274.625 cubic meters of material. Calculate the amount of material left after using 50 cubic meters.

Okay, lets begin

The amount of material left is 224.625 cubic meters.

Explanation

To find the remaining material, we need to subtract the used material from the total amount:

274.625 - 50 = 224.625 cubic meters.

Well explained 👍

Problem 3

A bottle holds 274.625 cubic meters of volume. Another bottle holds a volume of 25 cubic meters. What would be the total volume if the bottles are combined?

Okay, lets begin

The total volume of the combined bottles is 299.625 cubic meters.

Explanation

Let’s add the volume of both bottles:

274.625 + 25 = 299.625 cubic meters.

Well explained 👍

Problem 4

When the cube root of 274.625 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?

Okay, lets begin

2 × 6.5 = 13 The cube of 13 = 2197

Explanation

When we multiply the cube root of 274.625 by 2, it results in a significant increase in the volume because the cube increases exponentially.

Well explained 👍

Problem 5

Find ∛(46 + 46).

Okay, lets begin

∛(46 + 46) = ∛92 ≈ 4.52

Explanation

As shown in the question ∛(46 + 46), we can simplify that by adding them. So, 46 + 46 = 92.

Then we use this step:

∛92 ≈ 4.52 to get the answer.

FAQs on 274.625 Cube Root

1.Can we find the Cube Root of 274.625?

No, we cannot find the cube root of 274.625 exactly as it is not a whole number. It is approximately 6.5.

2.Why is Cube Root of 274.625 irrational?

The cube root of 274.625 is irrational because its decimal value goes on without an end and does not repeat.

3.Is it possible to get the cube root of 274.625 as an exact number?

No, the cube root of 274.625 is not an exact number. It is a decimal that is about 6.5.

4.Can we find the cube root of any number using prime factorization?

Prime factorization method can be used to calculate the cube root of perfect cube numbers but it is not the right method for non-perfect cube numbers. For example, 2 × 2 × 2 = 8, so 8 is a perfect cube.

5.Is there any formula to find the cube root of a number?

Yes, the formula we use for the cube root of any number ‘a’ is a^(1/3).

Important Glossaries for Cube Root of 274.625

  • 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 274.625^(1/3), ⅓ is the exponent which denotes the cube root of 274.625.
     
  • 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 274.625 is irrational because its decimal form goes on continuously without repeating the numbers.
