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 this topic, we will discuss the square of 255.
The square of a number is the product of the number with itself. The square of 255 is 255 × 255. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 255², where 255 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 255 is 255 × 255 = 65,025.
Square of 255 in exponential form: 255²
Square of 255 in arithmetic form: 255 × 255
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.
In this method, we multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 255.
Step 1: Identify the number. Here, the number is 255.
Step 2: Multiplying the number by itself, we get, 255 × 255 = 65,025.
The square of 255 is 65,025.
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 255
So: 255² = 255 × 255 = 65,025
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 255.
Step 1: Enter the number in the calculator Enter 255 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 255 × 255
Step 3: Press the equal to button to find the answer Here, the square of 255 is 65,025.
Tips and Tricks for the Square of 255

Mistakes are common among kids when doing math, especially when it comes to finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Find the length of the square, where the area of the square is 65,025 cm².
The area of a square = a²
So, the area of a square = 65,025 cm²
So, the length = √65,025 = 255.
The length of each side = 255 cm
The length of a square is 255 cm. Because the area is 65,025 cm², the length is √65,025 = 255.
Sarah is planning to tile her square floor of length 255 feet. The cost to tile a foot is 10 dollars. How much will it cost to tile the full floor?
The length of the floor = 255 feet
The cost to tile 1 square foot of floor = 10 dollars.
To find the total cost to tile, we find the area of the floor,
Area of the floor = area of the square = a²
Here a = 255
Therefore, the area of the floor = 255² = 255 × 255 = 65,025.
The cost to tile the floor = 65,025 × 10 = 650,250.
The total cost = 650,250 dollars
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 650,250 dollars.
Find the area of a circle whose radius is 255 meters.
The area of the circle = 204,203.75 m²
The area of a circle = πr²
Here, r = 255
Therefore, the area of the circle = π × 255²
= 3.14 × 255 × 255
= 204,203.75 m².
The area of the square is 65,025 cm². Find the perimeter of the square.
The perimeter of the square is 1,020 cm.
The area of the square = a²
Here, the area is 65,025 cm²
The length of the side is √65,025 = 255
Perimeter of the square = 4a
Here, a = 255
Therefore, the perimeter = 4 × 255 = 1,020 cm.
Find the square of 256.
The square of 256 is 65,536.
The square of 256 is multiplying 256 by 256. So, the square = 256 × 256 = 65,536.
