The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and so on. In this topic, we will discuss the square of 351.
What is the Square of 351
The square of a number is the product of the number with itself. The square of 351 is 351 × 351. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 351², where 351 is the base and 2 is the exponent. The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25. The square of 351 is 351 × 351 = 123,201. Square of 351 in exponential form: 351² Square of 351 in arithmetic form: 351 × 351
How to Calculate the Value of Square of 351
The square of a number is found by multiplying the number by itself. So let’s learn how to find the square of a number. These are the common methods used to find the square of a number. By Multiplication Method Using a Formula Using a Calculator
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 351. Step 1: Identify the number. Here, the number is 351. Step 2: Multiplying the number by itself, we get, 351 × 351 = 123,201. The square of 351 is 123,201.
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 351. So: 351² = 351 × 351 = 123,201
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 351. Step 1: Enter the number in the calculator Enter 351 in the calculator. Step 2: Multiply the number by itself using the multiplication button (×) That is 351 × 351 Step 3: Press the equal to button to find the answer Here, the square of 351 is 123,201. Tips and Tricks for the Square of 351 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 351
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 will be using the formula.
The formula to find the square of the number is a². Instead, students may use 351² with (3+5+1)² or (300+50+1)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 351
Problem 1
Find the length of the square, where the area of the square is 123,201 cm².
The area of a square = a² So, the area of a square = 123,201 cm² So, the length = √123,201 = 351. The length of each side = 351 cm
Explanation
The length of a square is 351 cm. Because the area is 123,201 cm², the length is √123,201 = 351.
Problem 2
Sarah is planning to tile her square floor with a length of 351 feet. The cost to tile a foot is 2 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 351 feet The cost to tile 1 square foot of floor = 2 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 = 351 Therefore, the area of the floor = 351² = 351 × 351 = 123,201. The cost to tile the floor = 123,201 × 2 = 246,402. The total cost = 246,402 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 246,402 dollars.
Problem 3
Find the area of a circle whose radius is 351 meters.
The area of the circle = 386,207.31 m²
Explanation
The area of a circle = πr² Here, r = 351 Therefore, the area of the circle = π × 351² = 3.14 × 351 × 351 = 386,207.31 m².
Problem 4
The area of the square is 123,201 cm². Find the perimeter of the square.
The perimeter of the square is 1,404 cm.
Explanation
The area of the square = a² Here, the area is 123,201 cm² The length of the side is √123,201 = 351 Perimeter of the square = 4a Here, a = 351 Therefore, the perimeter = 4 × 351 = 1,404.
Problem 5
Find the square of 352.
The square of 352 is 123,904.
Explanation
The square of 352 is multiplying 352 by 352. So, the square = 352 × 352 = 123,904.
