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 843.

Cube of 843

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 by itself three times results in a negative number.

The cube of 843 can be written as 843³, which is the exponential form. Or it can also be written in arithmetic form as, 843 × 843 × 843.

How to Calculate the Value of Cube of 843

In order to check whether a number is a cube number or not, we can use the following three methods, such as 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 a number by combining it 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. 843³ = 843 × 843 × 843

Step 2: You get 598,714,907 as the answer. Hence, the cube of 843 is 598,714,907.

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 843 into two parts. Let a = 800 and b = 43, so a + b = 843

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

Step 3: Calculate each term

a³ = 800³

3a²b = 3 × 800² × 43

3ab² = 3 × 800 × 43²

b³ = 43³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(800 + 43)³ = 800³ + 3 × 800² × 43 + 3 × 800 × 43² + 43³

843³ = 512,000,000 + 82,560,000 + 44,352,000 + 79,507

843³ = 598,714,907

Step 5: Hence, the cube of 843 is 598,714,907.

Using a Calculator

To find the cube of 843 using a calculator, input the number 843 and use the cube function (if available) or multiply 843 × 843 × 843. This operation calculates the value of 843³, resulting in 598,714,907. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Input 843

Step 3: If the calculator has a cube function, press it to calculate 843³.

Step 4: If there is no cube function on the calculator, simply multiply 843 three times manually.

Step 5: The calculator will display 598,714,907.

Tips and Tricks for the Cube of 843

  • 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 843

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 843?

Okay, lets begin

The cube of 843 is 598,714,907 and the cube root of 843 is approximately 9.448.

Explanation

First, let’s find the cube of 843.

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 843³ = 598,714,907

Next, we must find the cube root of 843

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√843 ≈ 9.448

Hence the cube of 843 is 598,714,907 and the cube root of 843 is approximately 9.448.

Problem 2

If the side length of the cube is 843 cm, what is the volume?

Okay, lets begin

The volume is 598,714,907 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 843 for the side length: V = 843³ = 598,714,907 cm³.

Problem 3

How much larger is 843³ than 800³?

Okay, lets begin

843³ – 800³ = 86,714,907.

Explanation

First find the cube of 843, that is 598,714,907

Next, find the cube of 800, which is 512,000,000

Now, find the difference between them using the subtraction method. 598,714,907 – 512,000,000 = 86,714,907

Therefore, 843³ is 86,714,907 larger than 800³.

Problem 4

If a cube with a side length of 843 cm is compared to a cube with a side length of 43 cm, how much larger is the volume of the larger cube?

Okay, lets begin

The volume of the cube with a side length of 843 cm is 598,714,907 cm³

Explanation

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

Cubing 843 means multiplying 843 by itself three times: 843 × 843 = 710,649, and then 710,649 × 843 = 598,714,907.

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

Therefore, the volume of the cube is 598,714,907 cm³.

Problem 5

Estimate the cube 842.9 using the cube 843.

Okay, lets begin

The cube of 842.9 is approximately 598,714,907.

Explanation

First, identify the cube of 843, The cube of 843 is 843³ = 598,714,907.

Since 842.9 is only a tiny bit less than 843, the cube of 842.9 will be almost the same as the cube of 843.

The cube of 842.9 is approximately 598,714,907 because the difference between 842.9 and 843 is very small.
