Cube of 1009

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 1009 can be written as 1009³, which is the exponential form. Or it can also be written in arithmetic form as, 1009 × 1009 × 1009.

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.

1. By Multiplication Method
2. Using a Formula
3. Using a Calculator

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. 1009³ = 1009 × 1009 × 1009

Step 2: You get 1,027,297,729 as the answer. Hence, the cube of 1009 is 1,027,297,729.

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 1009 into two parts, as 1000 and 9. Let a = 1000 and b = 9, so a + b = 1009

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

Step 3: Calculate each term

a³ = 1000³

3a²b = 3 × 1000² × 9

3ab² = 3 × 1000 × 9²

b³ = 9³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(1000 + 9)³ = 1000³ + 3 × 1000² × 9 + 3 × 1000 × 9² + 9³

1009³ = 1,000,000,000 + 27,000,000 + 243,000 + 729

1009³ = 1,027,297,729

Step 5: Hence, the cube of 1009 is 1,027,297,729.

To find the cube of 1009 using a calculator, input the number 1009 and use the cube function (if available) or multiply 1009 × 1009 × 1009. This operation calculates the value of 1009³, resulting in 1,027,297,729. 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, 0, and 9

Step 3: If the calculator has a cube function, press it to calculate 1009³.

Step 4: If there is no cube function on the calculator, simply multiply 1009 three times manually.

Step 5: The calculator will display 1,027,297,729.

• 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.

• Binomial Formula: It is an algebraic expression used to expand the powers of a number, written as (a + b)ⁿ, where ‘n’ is a positive integer raised to the base. The formula is used to find the square and cube of a number.

• Cube of a Number: Multiplying a number by itself three times is called the cube of a number.

• Exponential Form: It is a way of expressing numbers using a base and an exponent (or power), where the exponent value indicates how many times the base is multiplied by itself. For example, 2³ represents 2 × 2 × 2 equal to 8.

• Perfect Cube: A perfect cube is a number that can be expressed as the cube of an integer.

• Volume of a Cube: It is the amount of space enclosed within a cube, calculated by cubing its side length (side³).
