When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used in while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 50.

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. 

How to Calculate the Value of Cube of 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
     

By Multiplication Method

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.

Using a Formula (a³)

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.

Using a Calculator

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.

Tips and Tricks for the Cube of 50

  • 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. 
     

Common Mistakes to Avoid When Calculating the Cube of 50

There are some typical errors that kids might make during the process of cubing a number. Let us take a look at five of the major mistakes that kids might make:

Problem 1

What is the cube and cube root of 50?

Okay, lets begin

 The cube of 50 is 125,000 and the cube root of 50 is 3.684.
 

Explanation

First, let’s find the cube of 50.

We know that cube of a number x, such that x3 = y

Where x is the given number, and y is the cubed value of that number

So, we get 503 = 125,000

Next, we must find the cube root of 50

 We know that cube root of a number x, such that x = y 

Where x is the given number, and y is the cube root value of the number

So, we get 50 = 3.684

Hence the cube of 50 is 125,000 and the cube root of 50 is approximately 3.684.

Problem 2

If the side length of the cube is 50 cm, what is the volume?

Okay, lets begin

The volume is 125,000 cm3.
 

Explanation

Use the volume formula for a cube V= Side3.

Substitute 50 for the side length: V = 503 = 125,000 cm3.

Problem 3

How much larger is 50³ than 40³?

Okay, lets begin

503 – 403 = 61,000.
 

Explanation

First find the cube of 503, that is 125,000

Next, find the cube of 403, which is 64,000

Now, find the difference between them using the subtraction method. 

125,000 – 64, 000 = 61,000


Therefore, the 503 is 61,000 larger than 403.

Problem 4

If a cube with a side length of 50 cm is compared to a cube with a side length of 10 cm, how much larger is the volume of the larger cube?

Okay, lets begin

 The volume of the cube with a side length of 50 cm is 125,000 cm3
 

Explanation

To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).

Cubing 50 means multiplying 50 by itself three times: 

50 x 50 = 2,500, and the 2,500 x  50 = 125,000. 

The unit of volume is cubic centimeters (cm3), because we are calculating the space inside the cube.

Therefore, the volume of the cube is 125,000 cm3.

Problem 5

Estimate the cube 49.9 using the cube 50.

Okay, lets begin

The cube of 49.9 is approximately 125,000

Explanation

First, identify the cube of 50

The cube of 50 is 503 = 125,000.

Since 49.9 is only a tiny bit less than 50, the cube of 49.9 will be almost the same as the cube of 50.

The cube of 49.9 is approximately 125,000 because the difference between 49.9 and 50 is very small. 

So, we can approximate the value as 125,000.
