Cube of 887

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 887 can be written as 887³, which is the exponential form. Or it can also be written in arithmetic form as 887 × 887 × 887.

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 cube the numbers faster and easier 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.

887³ = 887 × 887 × 887

Step 2: You get 698,337,303 as the answer.

Hence, the cube of 887 is 698,337,303.

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 887 into two parts, for example: 800 and 87.

Let a = 800 and b = 87, so a + b = 887.

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

Step 3: Calculate each term

a³ = 800³

3a²b = 3 × 800² × 87

3ab² = 3 × 800 × 87²

b³ = 87³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(800 + 87)³ = 800³ + 3 × 800² × 87 + 3 × 800 × 87² + 87³

887³ = 512,000,000 + 167,040,000 + 18,144,000 + 658,503

887³ = 698,337,303

Step 5: Hence, the cube of 887 is 698,337,303.

To find the cube of 887 using a calculator, input the number 887 and use the cube function (if available) or multiply 887 × 887 × 887. This operation calculates the value of 887³, resulting in 698,337,303. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Enter 887.

Step 3: If the calculator has a cube function, press it to calculate 887³.

Step 4: If there is no cube function on the calculator, simply multiply 887 three times manually.

Step 5: The calculator will display 698,337,303.

• 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.
