Cube of 587

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 587 can be written as 587³, which is the exponential form. Or it can also be written in arithmetic form as, 587 × 587 × 587.

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 kids to cube the 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 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. 587³ = 587 × 587 × 587

Step 2: You get 202,262,363 as the answer. Hence, the cube of 587 is 202,262,363.

The formula (a + b)³is a binomial formula for finding the cube of a number. The formula is expanded as (a³ + 3a²b + 3ab² + b³).

Step 1: Split the number 587 into two parts. Let a = 500 and  b = 87, so a + b = 587.

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

Step 3: Calculate each term: (a³ = 500³)

3a²b = 3 × 500² × 87

3ab² = 3 × 500 × 87²

b³ = 87³

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

(500 + 87)³ = 500³ + 3 × 500² × 87 + 3 × 500 × 87² + 87³

587³ = 125,000,000 + 65,250,000 + 11,353,500 + 658,503

587³ = 202,262,363

Step 5: Hence, the cube of 587 is 202,262,363.

To find the cube of 587 using a calculator, input the number 587 and use the cube function (if available) or multiply 587 × 587 × 587. This operation calculates the value of 587³, resulting in 202,262,363. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 5, 8, and 7

Step 3: If the calculator has a cube function, press it to calculate 587³.

Step 4: If there is no cube function on the calculator, simply multiply 587 three times manually.

Step 5: The calculator will display 202,262,363.

• 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) which equals 8.

• Multiplication Method: A mathematical technique that involves finding the product of numbers by combining them through repeated addition.

• Cube Root: The value that, when multiplied by itself three times, gives the original number.
