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 0.027 and explain the methods used.

What is the Cube Root of 0.027?

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, ∛0.027 is written as \(0.027^{1/3}\). The cube root is just the opposite operation of finding the cube of a number. For example: Assume ‘y’ as the cube root of 0.027, then \(y^3\) can be 0.027. Since the cube root of 0.027 is an exact value, we can write it as 0.3.

Finding the Cube Root of 0.027

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 0.027. 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 perfect cube, such as 0.027, we can use the prime factorization method or simple observation, as it is a perfect cube.

Cube Root of 0.027 by Prime Factorization

Let's find the cube root of 0.027 using the prime factorization method.

First, express 0.027 as a fraction: 0.027 = 27/1000.

Next, find the cube root of both the numerator and the denominator separately.

The cube root of 27 is 3, and the cube root of 1000 is 10.

Thus, ∛(27/1000) = 3/10 = 0.3.

The cube root of 0.027 is 0.3.

Common Mistakes and How to Avoid Them in the Cube Root of 0.027

Finding the perfect cube of a number without any errors can be a difficult task for the students. This happens for many reasons. Here are a few mistakes the students commonly make and the ways to avoid them:

Problem 1

Imagine you have a cube-shaped toy that has a total volume of 0.027 cubic meters. Find the length of one side of the cube equal to its cube root.

Okay, lets begin

Side of the cube = ∛0.027 = 0.3 meters

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 0.3 meters.

Well explained 👍

Problem 2

A company manufactures 0.027 cubic meters of a substance. Calculate the amount of substance left after using 0.007 cubic meters.

Okay, lets begin

The amount of substance left is 0.02 cubic meters.

Explanation

To find the remaining substance, we need to subtract the used amount from the total: 0.027 - 0.007 = 0.02 cubic meters.

Well explained 👍

Problem 3

A container holds 0.027 cubic meters of liquid. Another container holds a volume of 0.008 cubic meters. What would be the total volume if the containers are combined?

Okay, lets begin

The total volume of the combined containers is 0.035 cubic meters.

Explanation

Explanation: Let’s add the volume of both containers:

0.027 + 0.008 = 0.035 cubic meters.

Well explained 👍

Problem 4

When the cube root of 0.027 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?

Okay, lets begin

2 × 0.3 = 0.6 The cube of 0.6 = 0.216

Explanation

When we multiply the cube root of 0.027 by 2, it results in a new number whose cube is significantly larger than the original number because the cube increases exponentially.

Well explained 👍

Problem 5

Find ∛(0.027 + 0.027).

Okay, lets begin

∛(0.027 + 0.027) = ∛0.054 ≈ 0.38

Explanation

As shown in the question ∛(0.027 + 0.027), we can simplify that by adding them.

So, 0.027 + 0.027 = 0.054.

Then we use this step: ∛0.054 ≈ 0.38 to get the answer.

Important Glossaries for Cube Root of 0.027

  • 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 an exact number. For example: 0.3 × 0.3 × 0.3 = 0.027, therefore, 0.027 is a perfect cube.
     
  • Exponent: The exponent form of the number denotes the number of times a number can be multiplied by itself. In \(a^{1/3}\), ⅓ is the exponent which denotes the cube root of ‘a’.
     
  • Radical sign: The symbol that is used to represent a root which is expressed as (∛).
     
  • Fraction: A numerical quantity that is not a whole number, representing a part of a whole, like 27/1000 for 0.027.
