Step 2: Multiply the number by itself using the multiplication button (×). That is 392 × 392
Step 3: Press the equal to button to find the answer
Here, the square of 392 is 153,664.
Tips and Tricks for the Square of 392
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 392
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 392² with (3 + 9 + 2)² or (300 + 90 + 2)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 do regular practice to avoid errors.
Solved Examples on Square of 392
Problem 1
Find the side length of a square, where the area of the square is 153,664 cm².
The area of a square = a² So, the area of a square = 153,664 cm² So, the length = √153,664 = 392. The length of each side = 392 cm
Explanation
The length of a square is 392 cm.
Because the area is 153,664 cm², the length is √153,664 = 392.
Problem 2
Sarah plans to plant a square garden with each side measuring 392 meters. If the cost to plant each square meter is 2 dollars, how much will it cost to plant the entire garden?
The length of the garden = 392 meters The cost to plant 1 square meter of garden = 2 dollars. To find the total cost to plant, we find the area of the garden, Area of the garden = area of the square = a² Here a = 392 Therefore, the area of the garden = 392² = 392 × 392 = 153,664. The cost to plant the garden = 153,664 × 2 = 307,328. The total cost = 307,328 dollars
Explanation
To find the cost to plant the garden, we multiply the area of the garden by the cost to plant per square meter.
So, the total cost is 307,328 dollars.
Problem 3
Find the area of a circle whose radius is 392 meters.
The area of the circle = 483,094.4 m²
Explanation
The area of a circle = πr²
Here, r = 392
Therefore, the area of the circle = π × 392² = 3.14 × 392 × 392 = 483,094.4 m².
Problem 4
The area of a square is 153,664 cm². Find the perimeter of the square.
The perimeter of the square is 1,568 cm.
Explanation
The area of the square = a²
Here, the area is 153,664 cm²
The length of the side is √153,664 = 392
Perimeter of the square = 4a
Here, a = 392
Therefore, the perimeter = 4 × 392 = 1,568.
Problem 5
Find the square of 393.
The square of 393 is 154,449.
Explanation
The square of 393 is multiplying 393 by 393.
So, the square = 393 × 393 = 154,449.
