Cube of 384

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 384 can be written as 384³, which is the exponential form.

Or it can also be written in arithmetic form as, 384 × 384 × 384.

In order to check whether a number is a cube number or not, we can use the following three methods: multiplication method, 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 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. 384³ = 384 × 384 × 384

Step 2: You get 56,623,104 as the answer. Hence, the cube of 384 is 56,623,104.

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 384 into two parts, as 300 and 84. Let a = 300 and b = 84, so a + b = 384

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

Step 3: Calculate each term a³ = 300³ 3a²b = 3 × 300² × 84 3ab² = 3 × 300 × 84² b³ = 84³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (300 + 84)³ = 300³ + 3 × 300² × 84 + 3 × 300 × 84² + 84³ 384³ = 27,000,000 + 22,680,000 + 6,364,800 + 592,704 384³ = 56,637,504

Step 5: Hence, the cube of 384 is 56,637,504.

To find the cube of 384 using a calculator, input the number 384 and use the cube function (if available) or multiply 384 × 384 × 384. This operation calculates the value of 384³, resulting in 56,623,104. 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 8 and 4

Step 3: If the calculator has a cube function, press it to calculate 384³.

Step 4: If there is no cube function on the calculator, simply multiply 384 three times manually.

Step 5: The calculator will display 56,623,104.

• 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 equals to 8.
   
• Perfect Cube: A number that can be expressed as the product of three equal integers. For example, 27 is a perfect cube because it can be written as 3 × 3 × 3.
   
• Volume of a Cube: The amount of space inside a cube, calculated as the cube of its side length.
