How to Calculate the Value of Square of 518
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 518.
Step 1: Identify the number. Here, the number is 518.
Step 2: Multiplying the number by itself, we get, 518 × 518 = 268,324.
The square of 518 is 268,324.
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 518
So: 518² = 518 × 518 = 268,324
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 518.
Step 1: Enter the number in the calculator. Enter 518 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 518 × 518
Step 3: Press the equal to button to find the answer. Here, the square of 518 is 268,324.
Tips and Tricks for the Square of 518
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 518
Mistakes are common among students 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 518
Problem 1
Find the length of the square, where the area of the square is 268,324 cm².
The area of a square = a²
So, the area of a square = 268,324 cm²
So, the length = √268,324 = 518.
The length of each side = 518 cm
Explanation
The length of a square is 518 cm.
Because the area is 268,324 cm², the length is √268,324 = 518.
Problem 2
Tom is planning to paint his square wall of length 518 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 518 feet
The cost to paint 1 square foot of wall = 3 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 = 518
Therefore, the area of the wall = 518² = 518 × 518 = 268,324.
The cost to paint the wall = 268,324 × 3 = 804,972.
The total cost = 804,972 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 804,972 dollars.
Problem 3
Find the area of a circle whose radius is 518 meters.
The area of the circle = 843,446.88 m²
Explanation
The area of a circle = πr²
Here, r = 518
Therefore, the area of the circle = π × 518² = 3.14 × 518 × 518 = 843,446.88 m².
Problem 4
The area of the square is 268,324 cm². Find the perimeter of the square.
The perimeter of the square is 2,072 cm.
Explanation
The area of the square = a²
Here, the area is 268,324 cm²
The length of the side is √268,324 = 518
Perimeter of the square = 4a
Here, a = 518
Therefore, the perimeter = 4 × 518 = 2,072.
Problem 5
Find the square of 520.
The square of 520 is 270,400.
Explanation
The square of 520 is multiplying 520 by 520.
So, the square = 520 × 520 = 270,400.
