Cube of 1318

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 1318 can be written as 1318³, which is the exponential form. Or it can also be written in arithmetic form as 1318 × 1318 × 1318.

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 to cube 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 in mathematics is 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. 1318³ = 1318 × 1318 × 1318

Step 2: You get 2,292,274,632 as the answer. Hence, the cube of 1318 is 2,292,274,632.

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 1318 into two parts, as 1300 and 18. Let a = 1300 and b = 18, so a + b = 1318

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

Step 3: Calculate each term a³ = 1300³ 3a²b = 3 × 1300² × 18 3ab² = 3 × 1300 × 18² b³ = 18³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³

(1300 + 18)³ = 1300³ + 3 × 1300² × 18 + 3 × 1300 × 18² + 18³

1318³ = 2,197,000,000 + 911,400 + 1,221,600 + 5,832

1318³ = 2,292,274,632

Step 5: Hence, the cube of 1318 is 2,292,274,632.

To find the cube of 1318 using a calculator, input the number 1318 and use the cube function (if available) or multiply 1318 × 1318 × 1318. This operation calculates the value of 1318³, resulting in 2,292,274,632. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 1 followed by 3, 1, and 8.

Step 3: If the calculator has a cube function, press it to calculate 1318³.

Step 4: If there is no cube function on the calculator, simply multiply 1318 three times manually.

Step 5: The calculator will display 2,292,274,632.

• 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: 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: 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.

• Perfect Cube: A number that can be expressed as the product of three identical groups of equal prime factors.

• Volume of a Cube: The amount of space a cube occupies, calculated as the cube of its side length.
