Cube of 418

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 418 can be written as 418³, which is the exponential form.

Or it can also be written in arithmetic form as 418 × 418 × 418.

In order to check whether a number is a cube number or not, we can use the following three methods: the 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.

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. 418³ = 418 × 418 × 418 Step 2: You get 73,047,032 as the answer. Hence, the cube of 418 is 73,047,032.

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 418 into two parts. Let a = 400 and b = 18, so a + b = 418

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

Step 3: Calculate each term a³ = 400³ 3a²b = 3 × 400² × 18 3ab² = 3 × 400 × 18² b³ = 18³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (400 + 18)³ = 400³ + 3 × 400² × 18 + 3 × 400 × 18² + 18³ 418³ = 64,000,000 + 8,640,000 + 388,800 + 5,832 418³ = 73,047,032

Step 5: Hence, the cube of 418 is 73,047,032.

To find the cube of 418 using a calculator, input the number 418 and use the cube function (if available) or multiply 418 × 418 × 418. This operation calculates the value of 418³, resulting in 73,047,032. 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 1 and 8.

Step 3: If the calculator has a cube function, press it to calculate 418³.

Step 4: If there is no cube function on the calculator, simply multiply 418 three times manually.

Step 5: The calculator will display 73,047,032.

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.

• 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.

• 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.

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

• Cube Root: The number that produces a given number when cubed, such as ∛27 = 3.
