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 370 and explain the methods used.

What is the Cube Root of 370?

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, ∛370 is written as 370^(1/3).

The cube root is the inverse operation of cubing a number.

For example, if ‘y’ is the cube root of 370, then y³ = 370. Since the cube root of 370 is not an exact integer, we can approximate it as approximately 7.189.

Finding the Cube Root of 370

Finding the cube root of a number involves identifying the number that, when multiplied by itself three times, results in the target number.

We will explore different methods to find the cube root of 370. The common methods include: 

  • Prime factorization method 
     
  • Approximation method 
     
  • Subtraction method -
     
  • Halley’s method

Since 370 is not a perfect cube, Halley’s method is often utilized for better approximation.

Cube Root of 370 by Halley’s Method

Let's find the cube root of 370 using Halley’s method.

The formula is: ∛a ≅ x((x³ + 2a) / (2x³ + a)), where: - a = the number for which the cube root is being calculated - x = an initial guess close to the cube root

Substituting,

a = 370;

x = 7 ∛a ≅ 7((7³ + 2 × 370) / (2 × 7³ + 370))

∛370 ≅ 7((343 + 740) / (686 + 370))

∛370 ≅ 7.189

The cube root of 370 is approximately 7.189.

Common Mistakes and How to Avoid Them in the Cube Root of 370

Finding the cube root of a number without any errors can be challenging for students.

This happens for various reasons.

Here are a few common mistakes and ways to avoid them:

Download Worksheets

Problem 1

Imagine you have a cube-shaped toy that has a total volume of 370 cubic centimeters. Find the length of one side of the box equal to its cube root.

Okay, lets begin

Side of the cube = ∛370 = 7.19 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 7.19 units.

Well explained 👍

Problem 2

A company manufactures 370 cubic meters of material. Calculate the amount of material left after using 120 cubic meters.

Okay, lets begin

The amount of material left is 250 cubic meters.

Explanation

To find the remaining material, subtract the used material from the total amount: 370 - 120 = 250 cubic meters.

Well explained 👍

Problem 3

A bottle holds 370 cubic meters of volume. Another bottle holds a volume of 80 cubic meters. What would be the total volume if the bottles are combined?

Okay, lets begin

The total volume of the combined bottles is 450 cubic meters.

Explanation

Add the volume of both bottles: 370 + 80 = 450 cubic meters.

Well explained 👍

Problem 4

When the cube root of 370 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?

Okay, lets begin

2 × 7.19 = 14.38 The cube of 14.38 = 2971.7

Explanation

Multiplying the cube root of 370 by 2 results in a significant increase in volume since the new value is cubed, increasing exponentially.

Well explained 👍

Problem 5

Find ∛(46 + 324).

Okay, lets begin

∛(46 + 324) = ∛370 ≈ 7.19

Explanation

As shown in the question, ∛(46 + 324), we can simplify this by adding them.

So, 46 + 324 = 370.

Then we use this step: ∛370 ≈ 7.19 to get the answer.

FAQs on Cube Root of 370

1.Can we find the Cube Root of 370?

No, we cannot find the cube root of 370 exactly as the cube root of 370 is not a whole number.

It is approximately 7.189.

2.Why is Cube Root of 370 irrational?

The cube root of 370 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 370 as an exact number?

No, the cube root of 370 is not an exact number.

It is a decimal that is about 7.189.

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

The 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, one formula we use for the cube root of any number ‘a’ is Halley’s method formula, which can approximate the cube root using iterations for non-perfect cubes.

Important Glossaries for Cube Root of 370

  • 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 370^(1/3), ⅓ is the exponent which denotes the cube root of 370.
  • Radical sign: The symbol that is used to represent a root is expressed as (∛).
  • Irrational number: Numbers that cannot be expressed as fractions are irrational. For example, the cube root of 370 is irrational because its decimal form goes on continuously without repeating.
