We write it in math as 635², where 635 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 635 is 635 × 635 = 403,225.
Square of 635 in exponential form: 635²
Square of 635 in arithmetic form: 635 × 635
How to Calculate the Value of Square of 635
The square of a number is found by multiplying the number by itself. 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
- Using a Calculator
By the Multiplication method
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 635.
Step 1: Identify the number. Here, the number is 635.
Step 2: Multiply the number by itself, we get: 635 × 635 = 403,225.
The square of 635 is 403,225.
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 635. So: 635² = 635 × 635 = 403,225.
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 635.
Step 1: Enter the number in the calculator Enter 635 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 635 × 635.
Step 3: Press the equal button to find the answer. Here, the square of 635 is 403,225.
Tips and Tricks for the Square of 635

Solved Examples on Square of 635
Problem 1
Find the length of a square, where the area of the square is 403,225 cm².
The area of a square = a²
So, the area of a square = 403,225 cm²
So, the length = √403,225 = 635.
The length of each side = 635 cm.
Explanation
The length of a square is 635 cm.
Because the area is 403,225 cm², the length is √403,225 = 635.
Problem 2
Sarah is planning to carpet her square room of length 635 feet. The cost to carpet a foot is 5 dollars. Then how much will it cost to carpet the full room?
The length of the room = 635 feet
The cost to carpet 1 square foot of the room = 5 dollars.
To find the total cost to carpet, we find the area of the room,
Area of the room = area of the square = a²
Here a = 635 Therefore, the area of the room = 635² = 635 × 635 = 403,225.
The cost to carpet the room = 403,225 × 5 = 2,016,125.
The total cost = 2,016,125 dollars.
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot. So, the total cost is 2,016,125 dollars.
Problem 3
Find the area of a circle whose radius is 635 meters.
The area of the circle = 1,266,190.25 m²
Explanation
The area of a circle = πr²
Here, r = 635
Therefore, the area of the circle = π × 635² = 3.14 × 635 × 635 = 1,266,190.25 m².
Problem 4
The area of a square is 403,225 cm². Find the perimeter of the square.
The perimeter of the square is 2,540 cm.
Explanation
The area of the square = a²
Here, the area is 403,225 cm²
The length of the side is √403,225 = 635
Perimeter of the square = 4a
Here, a = 635
Therefore, the perimeter = 4 × 635 = 2,540 cm.
Problem 5
Find the square of 636.
The square of 636 is 404,496.
Explanation
The square of 636 is found by multiplying 636 by 636.
So, the square = 636 × 636 = 404,496.
