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 403.
The square of a number is the product of the number itself.
The square of 403 is 403 × 403.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 403², where 403 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 403 is 403 × 403 = 162,409.
Square of 403 in exponential form: 403²
Square of 403 in arithmetic form: 403 × 403
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 403
Step 1: Identify the number. Here, the number is 403
Step 2: Multiplying the number by itself, we get, 403 × 403 = 162,409.
The square of 403 is 162,409.
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 403 So: 403² = 403 × 403 = 162,409
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 403.
Step 1: Enter the number in the calculator Enter 403 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 403 × 403
Step 3: Press the equal to button to find the answer Here, the square of 403 is 162,409.
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 162,409 cm².
The area of a square = a² So, the area of a square = 162,409 cm² So, the length = √162,409 = 403. The length of each side = 403 cm
The length of a square is 403 cm.
Because the area is 162,409 cm², the length is √162,409 = 403.
Sam is planning to tile his square floor of length 403 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 = 403 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 = 403 Therefore, the area of the floor = 403² = 403 × 403 = 162,409. The cost to tile the floor = 162,409 × 5 = 812,045. The total cost = 812,045 dollars
To find the cost to tile the floor, we multiply the area of the floor by cost to tile per foot.
So, the total cost is 812,045 dollars.
Find the area of a circle whose radius is 403 meters.
The area of the circle = 510,706.69 m²
The area of a circle = πr²
Here, r = 403
Therefore, the area of the circle = π × 403² = 3.14 × 403 × 403 = 510,706.69 m².
The area of the square is 162,409 cm². Find the perimeter of the square.
The perimeter of the square is
The area of the square = a²
Here, the area is 162,409 cm²
The length of the side is √162,409 = 403
Perimeter of the square = 4a
Here, a = 403
Therefore, the perimeter = 4 × 403 = 1,612.
Find the square of 404.
The square of 404 is 163,216
The square of 404 is multiplying 404 by 404.
So, the square = 404 × 404 = 163,216
