Cube of 225

Professor Greenline Explaining Math Concepts

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 cubes of 225.

Cube of 225

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 225 can be written as 225³, which is the exponential form.

 

Or it can also be written in arithmetic form as, 225 × 225 × 225.

How to Calculate the Value of Cube of 225

To determine 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 cube 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. 225³ = 225 × 225 × 225

 

Step 2: Calculate the result. You get 11,390,625 as the answer.

 

Hence, the cube of 225 is 11,390,625.

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 225 into two parts, as 200 and 25. Let a = 200 and b = 25, so a + b = 225

 

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

 

Step 3: Calculate each term a³ = 200³ 3a²b = 3 × 200² × 25 3ab² = 3 × 200 × 25² b³ = 25³

 

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (200 + 25)³ = 200³ + 3 × 200² × 25 + 3 × 200 × 25² + 25³ 225³ = 8,000,000 + 3,000,000 + 375,000 + 15,625 225³ = 11,390,625

 

Step 5: Hence, the cube of 225 is 11,390,625.

Professor Greenline from BrightChamps

Using a Calculator

To find the cube of 225 using a calculator, input the number 225 and use the cube function (if available) or multiply 225 × 225 × 225. This operation calculates the value of 225³, resulting in 11,390,625. 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 2 and 5.

 

Step 3: If the calculator has a cube function, press it to calculate 225³.

 

Step 4: If there is no cube function on the calculator, simply multiply 225 three times manually.

 

Step 5: The calculator will display 11,390,625.

Problem 1

What is the cube and cube root of 225?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 225 is 11,390,625 and the cube root of 225 is approximately 6.082.

Explanation

First, let’s find the cube of 225.

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 225³ = 11,390,625 Next, we must find the cube root of 225

We know that the 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 ∛225 ≈ 6.082

Hence the cube of 225 is 11,390,625 and the cube root of 225 is approximately 6.082.

Problem 2

If the side length of the cube is 225 cm, what is the volume?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume is 11,390,625 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 225 for the side length: V = 225³ = 11,390,625 cm³.

Problem 3

How much larger is 225³ than 200³?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

225³ – 200³ = 3,390,625.

Explanation

First, find the cube of 225³, that is 11,390,625

Next, find the cube of 200³, which is 8,000,000

Now, find the difference between them using the subtraction method. 11,390,625 – 8,000,000 = 3,390,625

Therefore, 225³ is 3,390,625 larger than 200³.

Problem 4

If a cube with a side length of 225 cm is compared to a cube with a side length of 25 cm, how much larger is the volume of the larger cube?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume of the cube with a side length of 225 cm is 11,390,625 cm³

Explanation

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

Cubing 225 means multiplying 225 by itself three times: 225 × 225 = 50,625, and then 50,625 × 225 = 11,390,625.

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

Therefore, the volume of the cube is 11,390,625 cm³.

Problem 5

Estimate the cube of 224.9 using the cube of 225.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 224.9 is approximately 11,390,625.

Explanation

First, identify the cube of 225, The cube of 225 is 225³ = 11,390,625.

Since 224.9 is only a tiny bit less than 225, the cube of 224.9 will be almost the same as the cube of 225.

The cube of 224.9 is approximately 11,390,625 because the difference between 224.9 and 225 is very small.

So, we can approximate the value as 11,390,625.
