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 1089.

Cube of 1089

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 1089 can be written as 1089³, which is the exponential form. Or it can also be written in arithmetic form as, 1089 × 1089 × 1089.

How to Calculate the Value of Cube of 1089

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

  • Multiplication Method
     
  • Factor Formula (a³)
     
  • 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. 1089³ = 1089 × 1089 × 1089

Step 2: You get 1,291,467,969 as the answer.

Hence, the cube of 1089 is 1,291,467,969.

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 1089 into two parts, as 1000 and 89. Let a = 1000 and b = 89, so a + b = 1089

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

Step 3: Calculate each term a³ = 1000³ 3a²b = 3 × 1000² × 89 3ab² = 3 × 1000 × 89² b³ = 89³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (1000 + 89)³ = 1000³ + 3 × 1000² × 89 + 3 × 1000 × 89² + 89³ 1089³ = 1,000,000,000 + 267,000,000 + 23,721,000 + 704,969 1089³ = 1,291,467,969

Step 5: Hence, the cube of 1089 is 1,291,467,969.

Using a Calculator

To find the cube of 1089 using a calculator, input the number 1089 and use the cube function (if available) or multiply 1089 × 1089 × 1089. This operation calculates the value of 1089³, resulting in 1,291,467,969. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 1 followed by 0, 8, and 9

Step 3: If the calculator has a cube function, press it to calculate 1089³.

Step 4: If there is no cube function on the calculator, simply multiply 1089 three times manually.

Step 5: The calculator will display 1,291,467,969.

Tips and Tricks for the Cube of 1089

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 1089

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 1089?

Okay, lets begin

The cube of 1089 is 1,291,467,969 and the cube root of 1089 is approximately 10.79.

Explanation

First, let’s find the cube of 1089.

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 1089³ = 1,291,467,969

Next, we must find the cube root of 1089 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 ∛1089 ≈ 10.79 Hence the cube of 1089 is 1,291,467,969 and the cube root of 1089 is approximately 10.79.

Problem 2

If the side length of the cube is 1089 cm, what is the volume?

Okay, lets begin

The volume is 1,291,467,969 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 1089 for the side length: V = 1089³ = 1,291,467,969 cm³.

Problem 3

How much larger is 1089³ than 1000³?

Okay, lets begin

1089³ – 1000³ = 291,467,969.

Explanation

First find the cube of 1089, that is 1,291,467,969

Next, find the cube of 1000, which is 1,000,000,000

Now, find the difference between them using the subtraction method. 1,291,467,969 – 1,000,000,000 = 291,467,969

Therefore, the 1089³ is 291,467,969 larger than 1000³.

Problem 4

If a cube with a side length of 1089 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 1089 cm is 1,291,467,969 cm³

Explanation

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

Cubing 1089 means multiplying 1089 by itself three times: 1089 × 1089 = 1,185,921, and then 1,185,921 × 1089 = 1,291,467,969.

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

Therefore, the volume of the cube is 1,291,467,969 cm³.
