Cube of 1047

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 1047 can be written as 1047³, which is the exponential form. Or it can also be written in arithmetic form as 1047 × 1047 × 1047.

In order to check whether a number is a cube number or not, we can use the following three methods: multiplication method, a factor formula (a³), or by using a calculator. These three methods will help you cube the numbers faster and more easily 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. 1047³ = 1047 × 1047 × 1047

Step 2: Calculate the product to get the answer. Hence, the cube of 1047 is 1,148,688,423.

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 1047 into two parts, as a and b. Let a = 1000 and b = 47, so a + b = 1047

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

Step 3: Calculate each term a³ = 1000³ 3a²b = 3 × 1000² × 47 3ab² = 3 × 1000 × 47² b³ = 47³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (1000 + 47)³ = 1000³ + 3 × 1000² × 47 + 3 × 1000 × 47² + 47³ 1047³ = 1,000,000,000 + 141,000,000 + 6,627,000 + 103,823 1047³ = 1,148,688,423

Step 5: Hence, the cube of 1047 is 1,148,688,423.

To find the cube of 1047 using a calculator, input the number 1047 and use the cube function (if available) or multiply 1047 × 1047 × 1047. This operation calculates the value of 1047³, resulting in 1,148,688,423. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Enter 1047

Step 3: If the calculator has a cube function, press it to calculate 1047³.

Step 4: If there is no cube function on the calculator, simply multiply 1047 three times manually.

Step 5: The calculator will display 1,148,688,423.

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 8.

• Multiplication Method: A basic arithmetic operation used to calculate the product of numbers by adding a number to itself a specified number of times.

• Volume Formula for a Cube: The formula V = Side³ is used to calculate the space inside a cube, where "Side" is the length of one of the cube's sides.
