Cube of 402

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 while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 402.

Cube of 402 for Filipino Students

Cube of 402

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 402 can be written as 4023, which is the exponential form.

 

Or it can also be written in arithmetic form as, 402 × 402 × 402.

How to Calculate the Value of Cube of 402

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 more easily 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 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. 4023 = 402 × 402 × 402

 

Step 2: You get 65,029,608 as the answer. Hence, the cube of 402 is 65,029,608.

Professor Greenline from BrightChamps

Using a Formula (\(a^3\))

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 402 into two parts, such as (400) and (2). Let (a = 400) and (b = 2), so (a + b = 402)

 

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

 

Step 3: Calculate each term (a3 = 4003) (3a2b = 3 × 4002 × 2) (3ab2 = 3 × 400 × 22) (b3 = 23)

 

Step 4: Add all the terms together: (a + b)3 = a3 + 3a2b + 3ab2 + b3) (400 + 2)3 = 4003 + 3 × 4002 × 2 + 3 × 400 × 22 + 23) (4023 = 64,000,000 + 960,000 + 4,800 + 8) (4023 = 65,029,608)

 

Step 5: Hence, the cube of 402 is 65,029,608.

Professor Greenline from BrightChamps

Using a Calculator

To find the cube of 402 using a calculator, input the number 402 and use the cube function (if available) or multiply 402 × 402 × 402. This operation calculates the value of 4023, resulting in 65,029,608. It’s a quick way to determine the cube without manual computation.

 

Step 1: Ensure the calculator is functioning properly.

 

Step 2: Press 4 followed by 0 and 2.

 

Step 3: If the calculator has a cube function, press it to calculate 4023.

 

Step 4: If there is no cube function on the calculator, simply multiply 402 three times manually.

 

Step 5: The calculator will display 65,029,608.

Tips and Tricks for the Cube of 402

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.

Problem 1

What is the cube and cube root of 402?

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

The cube of 402 is 65,029,608 and the cube root of 402 is approximately 7.418.

Explanation

First, let’s find the cube of 402.

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

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

So, we get 4023= 65,029,608.

Next, we must find the cube root of 402.

We know that the cube root of a number x is such that ∛x = y

where x is the given number, and y is the cube root value of the number.

So, we get ∛402 ≈ 7.418.

Hence the cube of 402 is 65,029,608 and the cube root of 402 is approximately 7.418.

Problem 2

If the side length of the cube is 402 cm, what is the volume?

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

The volume is 65,029,608 cm³.

Explanation

Use the volume formula for a cube V = Side3.

Substitute 402 for the side length: V = 4023 = 65,029,608cm³.

Problem 3

How much larger is \(402^3\) than \(302^3\)?

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

4023 - 3023 = 47,161,608.

Explanation

First, find the cube of 4023, which is 65,029,608.

Next, find the cube of 3023, which is 17,868,000.

Now, find the difference between them using the subtraction method. 65,029,608 - 17,868,000 = 47,161,608.

Therefore, 4023 is 47,161,608 larger than 3023.

Problem 4

If a cube with a side length of 402 cm is compared to a cube with a side length of 102 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 402 cm is 65,029,608 cm³.

Explanation

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

Cubing 402 means multiplying 402 by itself three times: 402 × 402 × 402 = 65,029,608.

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

Therefore, the volume of the cube is 65,029,608 cm³.

Problem 5

Estimate the cube of 401.9 using the cube of 402.

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

The cube of 401.9 is approximately 65,029,608.

Explanation

First, identify the cube of 402.

The cube of 402 is 4023 = 65,029,608.

Since 401.9 is only a tiny bit less than 402, the cube of 401.9 will be almost the same as the cube of 402.

The cube of 401.9 is approximately 65,029,608 because the difference between 401.9 and 402 is very small.

So, we can approximate the value as 65,029,608.
