Cube of 903

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 903 can be written as 903³, which is the exponential form. Or it can also be written in arithmetic form as, 903 × 903 × 903.

In order 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 easier without feeling confused or stuck while evaluating the answers.

• By Multiplication Method
   
• Using a Formula
   
• 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. 9

03³ = 903 × 903 × 903

Step 2: You get 737,019,027 as the answer.

Hence, the cube of 903 is 737,019,027.

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 903 into two parts.

Let a = 900 and b = 3, so a + b = 903

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

Step 3: Calculate each term       

a³ = 900³       

3a²b = 3 × 900² × 3       

3ab² = 3 × 900 × 3²      

b³ = 3³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(900 + 3)³ = 900³ + 3 × 900² × 3 + 3 × 900 × 3² + 3³

903³ = 729,000,000 + 7,290,000 + 24,300 + 27

903³ = 737,019,027

Step 5: Hence, the cube of 903 is 737,019,027.

To find the cube of 903 using a calculator, input the number 903 and use the cube function (if available) or multiply 903 × 903 × 903. This operation calculates the value of 903³, resulting in 737,019,027. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 9 followed by 0 and 3

Step 3: If the calculator has a cube function, press it to calculate 903³.

Step 4: If there is no cube function on the calculator, simply multiply 903 three times manually.

Step 5: The calculator will display 737,019,027.

• 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, which equals 8.

• Cube Root: The cube root of a number is a value that, when multiplied by itself three times, gives the original number.

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