When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 258.

Cube of 258

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 258 can be written as 258³, which is the exponential form.

Or it can also be written in arithmetic form as 258 × 258 × 258.

How to Calculate the Value of Cube of 258

In order to check whether a number is a cube number or not, we can use the following three methods: 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

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. 258³ = 258 × 258 × 258

Step 2: You get 17,181,352 as the answer. Hence, the cube of 258 is 17,181,352.

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 258 into two parts, as a and b. Let a = 250 and b = 8, so a + b = 258

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

Step 3: Calculate each term a³ = 250³ 3a²b = 3 × 250² × 8 3ab² = 3 × 250 × 8² b³ = 8³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (250 + 8)³ = 250³ + 3 × 250² × 8 + 3 × 250 × 8² + 8³ 258³ = 15,625,000 + 1,500,000 + 48,000 + 512 258³ = 17,181,352

Step 5: Hence, the cube of 258 is 17,181,352.

Using a Calculator

To find the cube of 258 using a calculator, input the number 258 and use the cube function (if available) or multiply 258 × 258 × 258. This operation calculates the value of 258³, resulting in 17,181,352. 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 5 and 8

Step 3: If the calculator has a cube function, press it to calculate 258³.

Step 4: If there is no cube function on the calculator, simply multiply 258 three times manually.

Step 5: The calculator will display 17,181,352.

Tips and Tricks for the Cube of 258

  • 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 258

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 258?

Okay, lets begin

The cube of 258 is 17,181,352 and the cube root of 258 is approximately 6.349.

Explanation

First, let’s find the cube of 258.

We know that 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 258³ = 17,181,352 Next, we must find the cube root of 258

We know that cube root of a number ‘x’, such that ∛x = y

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

So, we get ∛258 = 6.349

Hence the cube of 258 is 17,181,352 and the cube root of 258 is approximately 6.349.

Problem 2

If the side length of the cube is 258 cm, what is the volume?

Okay, lets begin

The volume is 17,181,352 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 258 for the side length: V = 258³ = 17,181,352 cm³.

Problem 3

How much larger is 258³ than 250³?

Okay, lets begin

258³ - 250³ = 1,556,352.

Explanation

First, find the cube of 258³, which is 17,181,352

Next, find the cube of 250³, which is 15,625,000

Now, find the difference between them using the subtraction method 17,181,352 - 15,625,000 = 1,556,352

Therefore, 258³ is 1,556,352 larger than 250³.

Problem 4

If a cube with a side length of 258 cm is compared to a cube with a side length of 8 cm, how much larger is the volume of the larger cube?

Okay, lets begin

The volume of the cube with a side length of 258 cm is 17,181,352 cm³.

Explanation

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

Cubing 258 means multiplying 258 by itself three times: 258 × 258 = 66,564, and then 66,564 × 258 = 17,181,352.

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

Therefore, the volume of the cube is 17,181,352 cm³.

Problem 5

Estimate the cube of 257.9 using the cube of 258.

Okay, lets begin

The cube of 257.9 is approximately 17,181,352.

Explanation

First, identify the cube of 258,

The cube of 258 is 258³ = 17,181,352. Since 257.9 is only a tiny bit less than 258, the cube of 257.9 will be almost the same as the cube of 258.

The cube of 257.9 is approximately 17,181,352 because the difference between 257.9 and 258 is very small.

So, we can approximate the value as 17,181,352.
