Step 2: Multiply the number by itself using the multiplication button (×) That is 918 × 918
Step 3: Press the equal to button to find the answer Here, the square of 918 is 842724.
Tips and Tricks for the Square of 918
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 918
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 918² with (9+18)² or (900+18)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 918
Problem 1
Find the length of the square, where the area of the square is 842724 cm².
The area of a square = a² So, the area of a square = 842724 cm² So, the length = √842724 = 918. The length of each side = 918 cm
Explanation
The length of a square is 918 cm.
Because the area is 842724 cm² the length is √842724 = 918.
Problem 2
A farmer wants to fence his square field of length 918 meters. If the cost of fencing per meter is 5 dollars, what will be the total cost?
The length of the field = 918 meters The cost to fence 1 meter of the field = 5 dollars. To find the total cost to fence, we find the perimeter of the field, Perimeter of the field = perimeter of the square = 4a Here a = 918 Therefore, the perimeter = 4 × 918 = 3672 meters. The cost to fence the field = 3672 × 5 = 18360 dollars. The total cost = 18360 dollars
Explanation
To find the cost to fence the field, we multiply the perimeter of the field by the cost to fence per meter.
So, the total cost is 18360 dollars.
Problem 3
Find the area of a circle whose radius is 918 meters.
The area of the circle = 2645277.64 m²
Explanation
The area of a circle = πr²
Here, r = 918
Therefore, the area of the circle = π × 918² = 3.14 × 918 × 918 = 2645277.64 m².
Problem 4
The area of the square is 842724 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 842724 cm²
The length of the side is √842724 = 918
Perimeter of the square = 4a
Here, a = 918
Therefore, the perimeter = 4 × 918 = 3672 cm.
Problem 5
Find the square of 919.
The square of 919 is 844561
Explanation
The square of 919 is multiplying 919 by 919.
So, the square = 919 × 919 = 844561
