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
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 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.
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.
Mistake 2
Errors when using the formula.
The formula to find the square of the number is a². Instead, students may use (2 + 5)² or (250 + 5)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing square with square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, students should understand the concept that square and square root are inverse operations. The square of 5 is 25, and the square root of 25 is ±5.
Mistake 4
Errors in parentheses.
Ignoring the parentheses when finding the square of a number can lead to errors. So, students should understand parentheses and do the operations in the correct order to avoid errors.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should practice regularly to avoid errors.
Solved Examples on Square of 255
Problem 1
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
Explanation
The length of a square is 255 cm. Because the area is 65,025 cm², the length is √65,025 = 255.
Problem 2
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
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 650,250 dollars.
Problem 3
Find the area of a circle whose radius is 255 meters.
The area of the circle = 204,203.75 m²
Explanation
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.
Problem 4
The area of the square is 65,025 cm². Find the perimeter of the square.
The perimeter of the square is 1,020 cm.
Explanation
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.
Problem 5
Find the square of 256.
The square of 256 is 65,536.
Explanation
The square of 256 is multiplying 256 by 256. So, the square = 256 × 256 = 65,536.
