Cube of 1118

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 1118 can be written as 1118³, which is the exponential form. Or it can also be written in arithmetic form as, 1118 × 1118 × 1118.

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 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 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. 1118³ = 1118 × 1118 × 1118

Step 2: You get 1,398,211,832 as the answer. Hence, the cube of 1118 is 1,398,211,832.

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 1118 into two parts, as 1000 and 118. Let a = 1000 and b = 118, so a + b = 1118

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

Step 3: Calculate each term a³ = 1000³ 3a²b = 3 × 1000² × 118 3ab² = 3 × 1000 × 118² b³ = 118³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (1000 + 118)³ = 1000³ + 3 × 1000² × 118 + 3 × 1000 × 118² + 118³ 1118³ = 1,000,000,000 + 354,000,000 + 41,724,000 + 1,643,832 1118³ = 1,398,211,832

Step 5: Hence, the cube of 1118 is 1,398,211,832.

To find the cube of 1118 using a calculator, input the number 1118 and use the cube function (if available) or multiply 1118 × 1118 × 1118. This operation calculates the value of 1118³, resulting in 1,398,211,832. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 1, 1, 1, and 8

Step 3: If the calculator has a cube function, press it to calculate 1118³.

Step 4: If there is no cube function on the calculator, simply multiply 1118 three times manually.

Step 5: The calculator will display 1,398,211,832.

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 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: 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 cube of an integer.

• Volume: The amount of space occupied by a 3-dimensional object, often measured in cubic units.
