Cube of 149

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 149 can be written as 149³, which is the exponential form. Or it can also be written in arithmetic form as 149 × 149 × 149.

To determine if a number is a cube number, we can use the following three methods: multiplication method, a factor formula (a³), or by using a calculator. These three methods will help individuals cube 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. 149³ = 149 × 149 × 149

Step 2: You get 3,307,149 as the answer. Hence, the cube of 149 is 3,307,149.

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 149 into two parts, such as 140 and 9. Let a = 140 and b = 9, so a + b = 149

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

Step 3: Calculate each term a³ = 140³ 3a²b = 3 × 140² × 9 3ab² = 3 × 140 × 9² b³ = 9³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(140 + 9)³ = 140³ + 3 × 140² × 9 + 3 × 140 × 9² + 9³

149³ = 2,744,000 + 529,200 + 34,020 + 729

149³ = 3,307,149

Step 5: Hence, the cube of 149 is 3,307,149.

To find the cube of 149 using a calculator, input the number 149 and use the cube function (if available) or multiply 149 × 149 × 149. This operation calculates the value of 149³, resulting in 3,307,149. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 1, 4, and 9

Step 3: If the calculator has a cube function, press it to calculate 149³.

Step 4: If there is no cube function on the calculator, simply multiply 149 three times manually.

Step 5: The calculator will display 3,307,149.

• 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, 3² represents 3 × 3 equals 9.

• Perfect Cube: A number is a perfect cube if it can be expressed as the cube of an integer.

• Volume of a Cube: The space occupied by a cube, calculated using the formula V = Side³, where 'Side' is the length of one side of the cube.
