Cube of 424

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 424 can be written as 424³, which is the exponential form.

Or it can also be written in arithmetic form as, 424 × 424 × 424.

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 students cube numbers faster and easier without feeling confused or stuck while evaluating the answers.

• By Multiplication Method
   
• Using a Formula (a³)
   
• Using a Calculator

The multiplication method is a process in mathematics used to find the product of numbers by combining them through repeated multiplication. It is a fundamental operation that forms the basis for more complex mathematical concepts.

Step 1: Write down the cube of the given number. 424³ = 424 × 424 × 424

Step 2: You get 76,336,064 as the answer. Hence, the cube of 424 is 76,336,064.

The formula (a + b)³is a binomial formula for finding the cube of a number. The formula is expanded as \(a³ + 3a²b + 3ab² + b³.

Step 1: Split the number 424 into two parts. Let a = 400 and b = 24, so a + b = 424

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

Step 3: Calculate each term a³ = 400³ 3a²b = 3 × 400² × 24 3ab² = 3 × 400 × 24² b³ = 24³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (400 + 24)³ = 400³ + 3 × 400² × 24 + 3 × 400 × 24² + 24³ 424³ = 64,000,000 + 11,520,000 + 691,200 + 13,824 424³ = 76,336,064

Step 5: Hence, the cube of 424 is 76,336,064.

To find the cube of 424 using a calculator, input the number 424 and use the cube function (if available) or multiply 424 × 424 × 424. This operation calculates the value of 424³, resulting in 76,336,064. 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 2 and 4

Step 3: If the calculator has a cube function, press it to calculate 424³.

Step 4: If there is no cube function on the calculator, simply multiply 424 three times manually.

Step 5: The calculator will display 76,336,064.

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. 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 equals 8.

• Perfect Cube: A number that can be expressed as the product of an integer multiplied by itself twice more e.g., 2³ = 8.

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