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 the topic, we will discuss the square of 320.
The square of a number is the product of the number itself.
The square of 320 is 320 × 320.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 320², where 320 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 320 is 320 × 320 = 102,400.
Square of 320 in exponential form: 320²
Square of 320 in arithmetic form: 320 × 320
The square of a number is 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.
In this method, we will multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 320.
Step 1: Identify the number. Here, the number is 320
Step 2: Multiplying the number by itself, we get, 320 × 320 = 102,400.
The square of 320 is 102,400.
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 320
So: 320² = 320 × 320 = 102,400
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 320.
Step 1: Enter the number in the calculator. Enter 320 in the calculator.
Step 2: Multiply the number by itself using the multiplication button(×). That is 320 × 320
Step 3: Press the equal to button to find the answer. Here, the square of 320 is 102,400.
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.
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.
Find the length of the square, where the area of the square is 102,400 cm².
The area of a square = a²
So, the area of a square = 102,400 cm²
So, the length = √102,400 = 320.
The length of each side = 320 cm
The length of a square is 320 cm.
Because the area is 102,400 cm², the length is √102,400 = 320.
Anna is planning to tile her square floor of length 320 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 = 320 feet
The cost to tile 1 square foot of the 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 = 320.
Therefore, the area of the floor = 320² = 320 × 320 = 102,400.
The cost to tile the floor = 102,400 × 5 = 512,000.
The total cost = 512,000 dollars
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 512,000 dollars.
Find the area of a circle whose radius is 320 meters.
The area of the circle = 321,699.2 m²
The area of a circle = πr²
Here, r = 320
Therefore, the area of the circle = π × 320² = 3.14 × 320 × 320 = 321,699.2 m².
The area of the square is 102,400 cm². Find the perimeter of the square.
The perimeter of the square is 1,280 cm.
The area of the square = a²
Here, the area is 102,400 cm²
The length of the side is √102,400 = 320
Perimeter of the square = 4a
Here, a = 320
Therefore, the perimeter = 4 × 320 = 1,280.
Find the square of 321.
The square of 321 is 103,041
The square of 321 is multiplying 321 by 321.
So, the square = 321 × 321 = 103,041
