Cube of 324

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 324 can be written as 324³, which is the exponential form. Or it can also be written in arithmetic form as 324 × 324 × 324.

In order to check whether a number is a cube number or not, we can use the following three methods, such as the multiplication method, a factor formula (a³), or by using a calculator. These three methods will help kids 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. 324³ = 324 × 324 × 324

Step 2: You get 34,012,224 as the answer. Hence, the cube of 324 is 34,012,224.

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 324 into two parts. Let a = 320 and b = 4, so a + b = 324

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

Step 3: Calculate each term

a³ = 320³

3a²b = 3 × 320² × 4

3ab² = 3 × 320 × 4²

b³ = 4³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(320 + 4)³ = 320³ + 3 × 320² × 4 + 3 × 320 × 4² + 4³

324³ = 32,768,000 + 1,228,800 + 15,360 + 64

324³ = 34,012,224

Step 5: Hence, the cube of 324 is 34,012,224.

To find the cube of 324 using a calculator, input the number 324 and use the cube function (if available) or multiply 324 × 324 × 324. This operation calculates the value of 324³, resulting in 34,012,224. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 3 followed by 2 and 4

Step 3: If the calculator has a cube function, press it to calculate 324³.

Step 4: If there is no cube function on the calculator, simply multiply 324 three times manually.

Step 5: The calculator will display 34,012,224.

• 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, 3³ represents 3 × 3 × 3, which equals 27.

• Cube Root: The cube root of a number is a value that, when multiplied by itself twice, gives the original number. It is denoted as ³√x.

• Volume of a Cube: The amount of space inside the cube, calculated as the side length raised to the power of three (Side³).
