What is the Square of 636
The square of a number is the product of the number itself. The square of 636 is 636 × 636. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 636², where 636 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 636 is 636 × 636 = 404,496.
Square of 636 in exponential form: 636²
Square of 636 in arithmetic form: 636 × 636
How to Calculate the Value of Square of 636
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
- 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 636.
Step 1: Identify the number. Here, the number is 636.
Step 2: Multiplying the number by itself, we get, 636 × 636 = 404,496.
The square of 636 is 404,496.
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 636. So: 636² = 636 × 636 = 404,496
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 636.
Step 1: Enter the number in the calculator. Enter 636 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 636 × 636.
Step 3: Press the equal to button to find the answer. Here, the square of 636 is 404,496.
Tips and Tricks for the Square of 636
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 636
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 636
Problem 1
Find the length of the square, where the area of the square is 404,496 cm².
The area of a square = a²
So, the area of a square = 404,496 cm²
So, the length = √404,496 = 636.
The length of each side = 636 cm
Explanation
The length of a square is 636 cm.
Because the area is 404,496 cm², the length is √404,496 = 636.
Problem 2
Emma wants to tile her square floor with tiles of length 636 feet. If each tile costs 5 dollars, how much will it cost to tile the entire floor?
The length of the floor = 636 feet
The cost to tile 1 square foot of floor = 5 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 = 636
Therefore, the area of the floor = 636² = 636 × 636 = 404,496.
The cost to tile the floor = 404,496 × 5 = 2,022,480.
The total cost = 2,022,480 dollars
Explanation
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 2,022,480 dollars.
Problem 3
Find the area of a circle whose radius is 636 meters.
The area of the circle = 1,271,442.24 m²
Explanation
The area of a circle = πr²
Here, r = 636
Therefore, the area of the circle = π × 636² = 3.14 × 636 × 636 = 1,271,442.24 m².
Problem 4
The area of the square is 404,496 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 404,496 cm²
The length of the side is √404,496 = 636
Perimeter of the square = 4a
Here, a = 636
Therefore, the perimeter = 4 × 636 = 2,544.
Problem 5
Find the square of 637.
The square of 637 is 405,769
Explanation
The square of 637 is multiplying 637 by 637.
So, the square = 637 × 637 = 405,769
