Step 2: Multiply the number by itself using the multiplication button (×). That is 1872 × 1872.
Step 3: Press the equal to button to find the answer. Here, the square of 1872 is 3,504,384.
Tips and Tricks for the Square of 1872
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 1872
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 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 using the formula.
The formula to find the square of the number is a². Instead, students may use 1872 with (1+8+7+2)² or (1800+72)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing 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 errors.
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 1872
Problem 1
Find the length of a square, where the area of the square is 3,504,384 cm².
The area of a square = a²
So, the area of a square = 3,504,384 cm²
So, the length = √3,504,384 = 1872.
The length of each side = 1872 cm
Explanation
The length of a square is 1872 cm.
Because the area is 3,504,384 cm², the length is √3,504,384 = 1872.
Problem 2
A farmer wants to fence a square plot of land with a side length of 1872 meters. How much fencing material will he need if each meter costs 5 dollars?
The length of each side of the plot = 1872 meters
To find the total perimeter, we use the formula for the perimeter of a square:
Perimeter = 4a Here a = 1872
Therefore, the perimeter = 4 × 1872 = 7,488 meters.
The cost of fencing = 7,488 × 5 = 37,440 dollars.
The total cost = 37,440 dollars
Explanation
To find the cost of fencing the plot, we multiply the perimeter of the plot by the cost per meter.
So, the total cost is 37,440 dollars.
Problem 3
Find the area of a circle whose radius is 1872 meters.
The area of the circle = 11,021,924.16 m²
Explanation
The area of a circle = πr²
Here, r = 1872
Therefore, the area of the circle = π × 1872² = 3.14 × 1872 × 1872 = 11,021,924.16 m².
Problem 4
The area of a square is 3,504,384 cm². Find the perimeter of the square.
The perimeter of the square is 7,488 cm.
Explanation
The area of the square = a²
Here, the area is 3,504,384 cm²
The length of the side is √3,504,384 = 1872
Perimeter of the square = 4a
Here, a = 1872
Therefore, the perimeter = 4 × 1872 = 7,488 cm.
Problem 5
Find the square of 1873.
The square of 1873 is 3,508,129.
Explanation
The square of 1873 is multiplying 1873 by 1873.
So, the square = 1873 × 1873 = 3,508,129.
