Tips and Tricks for the Square of 876
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 876
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 will be using the formula.
The formula to find the square of the number is a². Instead, students may use 876² with (8 + 7 + 6)² or (800 + 70 + 6)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 876
Problem 1
Find the length of the square, where the area of the square is 767,376 cm².
The area of a square = a²
So, the area of a square = 767,376 cm²
So, the length = √767,376 = 876
The length of each side = 876 cm
Explanation
The length of a square is 876 cm.
Because the area is 767,376 cm², the length is √767,376 = 876.
Problem 2
Lisa has a square garden of length 876 meters. If she wants to plant flowers at 10 dollars per square meter, how much will it cost to cover the entire garden with flowers?
The length of the garden = 876 meters
The cost to plant flowers per square meter = 10 dollars.
To find the total cost to plant flowers, we find the area of the garden,
Area of the garden = area of the square = a²
Here a = 876
Therefore, the area of the garden = 876² = 876 × 876 = 767,376.
The cost to plant flowers = 767,376 × 10 = 7,673,760.
The total cost = 7,673,760 dollars
Explanation
To find the cost to plant flowers in the garden, we multiply the area of the garden by the cost to plant per meter. So, the total cost is 7,673,760 dollars.
Problem 3
Find the area of a circle whose radius is 876 meters.
The area of the circle = 2,413,716.16 m²
Explanation
The area of a circle = πr²
Here, r = 876
Therefore, the area of the circle = π × 876² = 3.14 × 876 × 876 = 2,413,716.16 m².
Problem 4
The area of the square is 767,376 cm². Find the perimeter of the square.
The perimeter of the square is 3,504 cm
Explanation
The area of the square = a²
Here, the area is 767,376 cm²
The length of the side is √767,376 = 876
Perimeter of the square = 4a
Here, a = 876
Therefore, the perimeter = 4 × 876 = 3,504 cm.
Problem 5
Find the square of 877.
The square of 877 is 769,129
Explanation
The square of 877 is multiplying 877 by 877.
So, the square = 877 × 877 = 769,129
