Cube of 163

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 163 can be written as 163³, which is the exponential form. Or it can also be written in arithmetic form as, 163 × 163 × 163.

To determine 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. 163³ = 163 × 163 × 163

Step 2: You get 4,329,887 as the answer. Hence, the cube of 163 is 4,329,887.

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 163 into two parts, as 160 and 3. Let a = 160 and b = 3, so a + b = 163

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

Step 3: Calculate each term

a³ = 160³

3a²b = 3 × 160² × 3

3ab² = 3 × 160 × 3²

b³ = 3³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (160 + 3)³ = 160³ + 3 × 160² × 3 + 3 × 160 × 3² + 3³ 163³ = 4,096,000 + 230,400 + 4,320 + 27 163³ = 4,329,887

Step 5: Hence, the cube of 163 is 4,329,887.

To find the cube of 163 using a calculator, input the number 163 and use the cube function (if available) or multiply 163 × 163 × 163. This operation calculates the value of 163³, resulting in 4,329,887. 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 6 and 3

Step 3: If the calculator has a cube function, press it to calculate 163³.

Step 4: If there is no cube function on the calculator, simply multiply 163 three times manually.

Step 5: The calculator will display 4,329,887.

• 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.

• Perfect Cube: A number that can be expressed as the cube of an integer.

• Cube Root: The cube root of a number is a value that, when multiplied by itself three times, gives the original number.
