Cube of 50

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 50 can be written as 50³, which is the exponential form. Or it can also be written in arithmetic form as, 50  x 50 x  50. 

In order to check whether a number is a cube number or not, we can use the following three methods, such as 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.

50³ = 50 x 50 x 50 

Step 2: You get 125,000 as the answer.

Hence, the cube of 50 is 125,000.

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 50 into two parts, as a and b.

 Let a = 40 and b = 10, so a + b = 50

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

Step 3: Calculate each term 

   a³= 40³

  3a²b = 3 x  40² x 10

 3ab² = 3 x 40  x 10²

 b³ = 10³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(40 + 10)³= 40³ + 3 x 40² x 10 + 3x  40 x 10² + 10³

50³ = 64000 + 48000 + 12000 + 1000

 50³ = 125000

Step 5: Hence, the cube of 50 is 125,000.

To find the cube of 50 using a calculator, input the number 50 and use the cube function (if available) or multiply 50x  50x  50. This operation calculates the value of 50³, resulting in 125,000. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 5 followed by 0

Step 3: If the calculator has a cube function, press it to calculate 50³.

Step 4: If there is no cube function on the calculator, simply multiply 50 three times manually.

Step 5: The calculator will display 125,000.

• 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 x 2 x 2 equals to 8.
