The square of a number is the product of the number itself.
The square of 380 is 380 × 380.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 380², where 380 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 380 is 380 × 380 = 144,400.
Square of 380 in exponential form: 380²
Square of 380 in arithmetic form: 380 × 380
How to Calculate the Value of Square of 380
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

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 380.
Step 1: Identify the number. Here, the number is 380.
Step 2: Multiplying the number by itself, we get, 380 × 380 = 144,400.
The square of 380 is 144,400.
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 380
So: 380² = 380 × 380 = 144,400
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 380.
Step 1: Enter the number in the calculator Enter 380 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 380 × 380
Step 3: Press the equal to button to find the answer
Here, the square of 380 is 144,400.
Tips and Tricks for the Square of 380
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

Common Mistakes to Avoid When Calculating the Square of 380
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 swap 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 380
Problem 1
Find the length of the square, where the area of the square is 144,400 cm².
The area of a square = a² So, the area of a square = 144,400 cm² So, the length = √144,400 = 380. The length of each side = 380 cm
Explanation
The length of a square is 380 cm.
Because the area is 144,400 cm², the length is √144,400 = 380.
Problem 2
Alex is planning to paint his square wall of length 380 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 = 380 feet The cost to paint 1 square foot of wall = 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 = 380 Therefore, the area of the wall = 380² = 380 × 380 = 144,400. The cost to paint the wall = 144,400 × 2 = 288,800. The total cost = 288,800 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 288,800 dollars.
Problem 3
Find the area of a circle whose radius is 380 meters.
The area of the circle = 453,760 m²
Explanation
The area of a circle = πr²
Here, r = 380
Therefore, the area of the circle = π × 380² = 3.14 × 380 × 380 = 453,760 m².
Problem 4
The area of the square is 144,400 cm². Find the perimeter of the square.
The perimeter of the square is 1,520 cm.
Explanation
The area of the square = a²
Here, the area is 144,400 cm²
The length of the side is √144,400 = 380
Perimeter of the square = 4a
Here, a = 380
Therefore, the perimeter = 4 × 380 = 1,520 cm.
Problem 5
Find the square of 381.
The square of 381 is 145,161.
Explanation
The square of 381 is multiplying 381 by 381.
So, the square = 381 × 381 = 145,161.
