Cube of 146

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 146 can be written as 146³, which is the exponential form.

Or it can also be written in arithmetic form as, 146 × 146 × 146.

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 to 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 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. 146³ = 146 × 146 × 146

Step 2: You get 3,115,336 as the answer. Hence, the cube of 146 is 3,115,336.

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 146 into two parts, as 140 and 6. Let a = 140 and b = 6, so a + b = 146

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

Step 3: Calculate each term: a³ = 140³ 3a²b = 3 × 140² × 6 3ab² = 3 × 140 × 6² b³ = 6³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (140 + 6)³ = 140³ + 3 × 140² × 6 + 3 × 140 × 6² + 6³ 146³ = 2,744,000 + 352,800 + 15,120 + 216

Step 5: Hence, the cube of 146 is 3,115,136.

To find the cube of 146 using a calculator, input the number 146 and use the cube function (if available) or multiply 146 × 146 × 146. This operation calculates the value of 146³, resulting in 3,115,336. 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 4 and then 6.

Step 3: If the calculator has a cube function, press it to calculate 146³.

Step 4: If there is no cube function on the calculator, simply multiply 146 three times manually.

Step 5: The calculator will display 3,115,336.

• 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.
   
• Cube Root: The value that, when multiplied by itself three times, gives the original number.
   
• Perfect Cube: A number that can be expressed as the cube of an integer.
