Square of 300
The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and so on. In the topic, we will discuss the square of 300.
What is the Square of 300
The square of a number is the product of the number itself.
The square of 300 is 300 × 300.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 300², where 300 is the base and 2 is the exponent.
The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25.
The square of 300 is 300 × 300 = 90000.
Square of 300 in exponential form: 300²
Square of 300 in arithmetic form: 300 × 300
How to Calculate the Value of Square of 300
The square of a number is multiplying the number by itself. So let’s learn how to find the square of a number. These are the common methods used to find the square of a number.
- By Multiplication Method
- Using a Formula (a2)
- Using a Calculator
By the Multiplication method
In this method, we will multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 300.
Step 1: Identify the number. Here, the number is 300
Step 2: Multiplying the number by itself, we get, 300 × 300 = 90000.
The square of 300 is 90000.
Using a Formula (a²)
In this method, the formula, a² is used to find the square of the number. Where a is the number.
Step 1: Understanding the equation Square of a number = a²
a² = a × a
Step 2: Identifying the number and substituting the value in the equation.
Here, ‘a’ is 300
So: 300² = 300 × 300 = 90000
By Using a Calculator
Using a calculator to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 300.
Step 1: Enter the number in the calculator. Enter 300 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 300 × 300
Step 3: Press the equal to button to find the answer. Here, the square of 300 is 90000.
Tips and Tricks for the Square of 300
Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students.
- The square of an even number is always an even number. For example, 6² = 36
- The square of an odd number is always an odd number. For example, 5² = 25
- The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9.
- If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, √1.44 = 1.2
- The square root of a perfect square is always a whole number. For example, √144 = 12.
Common Mistakes to Avoid When Calculating the Square of 300
Mistakes are common among kids when doing math, especially when it is finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or else by swapping the digits. To avoid it, students should double-check the answer. They can double-check by finding the square root of the solution they found.
For example, the square of 25 is 625, and the square root of 625 is ±25.
Solved Examples on Square of 300
Problem 1
Find the length of the square, where the area of the square is 90000 cm².
The area of a square = a²
So, the area of a square = 90000 cm²
So, the length = √90000 = 300.
The length of each side = 300 cm
Explanation
The length of a square is 300 cm.
Because the area is 90000 cm² the length is √90000 = 300.
Problem 2
Sara is planning to paint her square wall of length 300 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 300 feet
The cost to paint 1 square foot of wall = is 2 dollars.
To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a²
Here a = 300
Therefore, the area of the wall = 300² = 300 × 300 = 90000.
The cost to paint the wall = 90000 × 2 = 180000.
The total cost = 180000 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 180000 dollars.
Problem 3
Find the area of a circle whose radius is 300 meters.
The area of the circle = 282743.3 m²
Explanation
The area of a circle = πr²
Here, r = 300
Therefore, the area of the circle = π × 300² = 3.14 × 300 × 300 = 282743.3 m².
Problem 4
The area of the square is 90000 cm². Find the perimeter of the square.
The perimeter of the square is 1200 cm.
Explanation
The area of the square = a²
Here, the area is 90000 cm²
The length of the side is √90000 = 300
Perimeter of the square = 4a
Here, a = 300
Therefore, the perimeter = 4 × 300 = 1200.
Problem 5
Find the square of 301.
The square of 301 is 90601.
Explanation
The square of 301 is multiplying 301 by 301.
So, the square = 301 × 301 = 90601
