By the Multiplication method
In this method, we multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 862.
Step 1: Identify the number. Here, the number is 862.
Step 2: Multiplying the number by itself, we get, 862 × 862 = 743,044.
The square of 862 is 743,044.
Using a Formula (a²)
In this method, the formula a² is used to find the square of the number, where a is the number.
Step 1: Understanding the equation Square of a number = a²
a² = a × a
Step 2: Identifying the number and substituting the value in the equation.
Here, ‘a’ is 862. So: 862² = 862 × 862 = 743,044.
By Using a Calculator
Using a calculator to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 862.
Step 1: Enter the number in the calculator. Enter 862 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 862 × 862.
Step 3: Press the equal to button to find the answer. Here, the square of 862 is 743,044.
Tips and Tricks for the Square of 862
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 862
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 862² with (8+6+2)² or (800+60+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 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 862
Problem 1
Find the length of the square, where the area of the square is 743,044 cm².
The area of a square = a²
So, the area of a square = 743,044 cm²
So, the length = √743,044 = 862.
The length of each side = 862 cm
Explanation
The length of a square is 862 cm. Because the area is 743,044 cm², the length is √743,044 = 862.
Problem 2
Sarah is planning to tile her square kitchen floor of length 862 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 862 feet
The cost to tile 1 square foot of floor = 5 dollars.
To find the total cost to tile, we find the area of the floor.
Area of the floor = area of the square = a²
Here a = 862
Therefore, the area of the floor = 862² = 862 × 862 = 743,044.
The cost to tile the floor = 743,044 × 5 = 3,715,220.
The total cost = 3,715,220 dollars.
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 3,715,220 dollars.
Problem 3
Find the area of a circle whose radius is 862 meters.
The area of the circle = 2,334,198.36 m²
Explanation
The area of a circle = πr²
Here, r = 862
Therefore, the area of the circle = π × 862² = 3.14 × 862 × 862 = 2,334,198.36 m².
Problem 4
The area of the square is 743,044 cm². Find the perimeter of the square.
The perimeter of the square is 3,448 cm.
Explanation
The area of the square = a²
Here, the area is 743,044 cm²
The length of the side is √743,044 = 862
Perimeter of the square = 4a
Here, a = 862
Therefore, the perimeter = 4 × 862 = 3,448.
Problem 5
Find the square of 863.
The square of 863 is 744,769.
Explanation
The square of 863 is multiplying 863 by 863. So, the square = 863 × 863 = 744,769.
