Tips and Tricks for the Square of 676
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 676
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.
Mistake 2
Errors when using the formula.
The formula to find the square of the number is a². Instead, students may use 676² with (67 + 6)² or (600 + 76)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and 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 error.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should do regular practice to avoid errors.
Solved Examples on Square of 676
Problem 1
Find the length of the square, where the area of the square is 456976 cm².
The area of a square = a²
So, the area of a square = 456976 cm²
So, the length = √456976 = 676.
The length of each side = 676 cm
Explanation
The length of a square is 676 cm. Because the area is 456976 cm² the length is √456976 = 676.
Problem 2
A farmer wants to plant a square field with side length 676 meters. The cost to plant a square meter is 0.5 dollars. How much will it cost to plant the entire field?
The length of the field = 676 meters
The cost to plant 1 square meter of field = 0.5 dollars.
To find the total cost to plant, we find the area of the field,
Area of the field = area of the square = a²
Here a = 676
Therefore, the area of the field = 676² = 676 × 676 = 456976.
The cost to plant the field = 456976 × 0.5 = 228488.
The total cost = 228488 dollars
Explanation
To find the cost to plant the field, we multiply the area of the field by the cost to plant per square meter. So, the total cost is 228488 dollars.
Problem 3
Find the area of a circle whose radius is 676 meters.
The area of the circle = 1,437,089.76 m²
Explanation
The area of a circle = πr²
Here, r = 676
Therefore, the area of the circle = π × 676²
= 3.14 × 676 × 676
= 1,437,089.76 m².
Problem 4
The area of a square is 456,976 cm². Find the perimeter of the square.
The perimeter of the square is 2704 cm.
Explanation
The area of the square = a²
Here, the area is 456,976 cm²
The length of the side is √456,976 = 676
Perimeter of the square = 4a
Here, a = 676
Therefore, the perimeter = 4 × 676 = 2704.
Problem 5
Find the square of 677.
The square of 677 is 458329.
Explanation
The square of 677 is multiplying 677 by 677. So, the square = 677 × 677 = 458329.
