When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used when comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about the cube of 238.

Cube of 238

A cube number is a value obtained by raising a number to the power of 3, or by multiplying the number by itself three times.

When you cube a positive number, the result is always positive.

When you cube a negative number, the result is always negative.

This is because a negative number multiplied by itself three times results in a negative number.

The cube of 238 can be written as 238³, which is the exponential form.

Or it can also be written in arithmetic form as, 238 × 238 × 238.

How to Calculate the Value of Cube of 238

In order to check whether a number is a cube number or not, we can use the following three methods, such as the multiplication method, a factor formula (a³), or by using a calculator. These three methods will help kids to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.

  • By Multiplication Method
     
  • Using a Formula (a3)
     
  • Using a Calculator

By Multiplication Method

The multiplication method is a process in mathematics used to find the product of two numbers or quantities by combining them through repeated addition. It is a fundamental operation that forms the basis for more complex mathematical concepts.

Step 1: Write down the cube of the given number. 238³ = 238 × 238 × 238

Step 2: You get 13,472,872 as the answer.

Hence, the cube of 238 is 13,472,872.

Using a Formula (a³)

The formula (a + b)³ is a binomial formula for finding the cube of a number. The formula is expanded as a³ + 3a²b + 3ab² + b³.

Step 1: Split the number 238 into two parts, as 230 and 8. Let a = 230 and b = 8, so a + b = 238

Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³

Step 3: Calculate each term a³ = 230³ 3a²b = 3 × 230² × 8 3ab² = 3 × 230 × 8² b³ = 8³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (230 + 8)³ = 230³ + 3 × 230² × 8 + 3 × 230 × 8² + 8³ 238³ = 12,167,000 + 127,920 + 44,160 + 512 238³ = 13,472,872

Step 5: Hence, the cube of 238 is 13,472,872.

Using a Calculator

To find the cube of 238 using a calculator, input the number 238 and use the cube function (if available) or multiply 238 × 238 × 238. This operation calculates the value of 238³, resulting in 13,472,872. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 2 followed by 3 and then 8

Step 3: If the calculator has a cube function, press it to calculate 238³.

Step 4: If there is no cube function on the calculator, simply multiply 238 three times manually.

Step 5: The calculator will display 13,472,872.

Tips and Tricks for the Cube of 238

  • The cube of any even number is always even, while the cube of any odd number is always odd.
     
  • The product of two or more perfect cube numbers is always a perfect cube.
     
  • A perfect cube can always be expressed as the product of three identical groups of equal prime factors.

Common Mistakes to Avoid When Calculating the Cube of 238

There are some typical errors that kids might make during the process of cubing a number. Let us take a look at five of the major mistakes that kids might make:

Problem 1

What is the cube and cube root of 238?

Okay, lets begin

The cube of 238 is 13,472,872 and the cube root of 238 is approximately 6.2.

Explanation

First, let’s find the cube of 238.

We know that the cube of a number, such that x³ = y

Where x is the given number, and y is the cubed value of that number

So, we get 238³ = 13,472,872 Next, we must find the cube root of 238

We know that the cube root of a number ‘x’, such that ³√x = y

Where ‘x’ is the given number, and y is the cube root value of the number

So, we get ³√238 ≈ 6.2

Hence the cube of 238 is 13,472,872 and the cube root of 238 is approximately 6.2.

Problem 2

If the side length of the cube is 238 cm, what is the volume?

Okay, lets begin

The volume is 13,472,872 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 238 for the side length: V = 238³ = 13,472,872 cm³.

Problem 3

How much larger is 238³ than 230³?

Okay, lets begin

238³ – 230³ = 1,305,872.

Explanation

First, find the cube of 238³, which is 13,472,872

Next, find the cube of 230³, which is 12,167,000

Now, find the difference between them using the subtraction method. 13,472,872 – 12,167,000 = 1,305,872

Therefore, 238³ is 1,305,872 larger than 230³.

Problem 4

If a cube with a side length of 238 cm is compared to a cube with a side length of 10 cm, how much larger is the volume of the larger cube?

Okay, lets begin

The volume of the cube with a side length of 238 cm is 13,472,872 cm³

Explanation

To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).

Cubing 238 means multiplying 238 by itself three times: 238 × 238 = 56,644, and then 56,644 × 238 = 13,472,872.

The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.

Therefore, the volume of the cube is 13,472,872 cm³.

Problem 5

Estimate the cube of 237.9 using the cube of 238.

Okay, lets begin

The cube of 237.9 is approximately 13,472,872.

Explanation

First, identify the cube of 238,

The cube of 238 is 238³ = 13,472,872.

Since 237.9 is only a tiny bit less than 238, the cube of 237.9 will be almost the same as the cube of 238.

The cube of 237.9 is approximately 13,472,872 because the difference between 237.9 and 238 is very small.

So, we can approximate the value as 13,472,872.
