The product of multiplying an integer by itself is the square of a number. Squares are used in programming, calculating areas, and more. In this topic, we will discuss the square of 804.
The square of a number is the product of the number by itself.
The square of 804 is 804 × 804.
We write it in math as 804², where 804 is the base and 2 is the exponent.
The square of a positive and a negative number is always positive.
For example, 5² = 25; (-5)² = 25.
The square of 804 is 804 × 804 = 646,416.
Square of 804 in exponential form: 804²
Square of 804 in arithmetic form: 804 × 804
The square of a number is multiplying the number by itself. 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 804.
Step 1: Identify the number. Here, the number is 804.
Step 2: Multiply the number by itself. 804 × 804 = 646,416.
The square of 804 is 646,416.
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 804.
So: 804² = 804 × 804 = 646,416

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 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 646,416 cm².
The area of a square = a² So, the area of a square = 646,416 cm² So, the length = √646,416 = 804. The length of each side = 804 cm
The length of a square is 804 cm.
Because the area is 646,416 cm², the length is √646,416 = 804.
Lisa plans to carpet her square room with a length of 804 feet. The cost to carpet a foot is 5 dollars. How much will it cost to carpet the full room?
The length of the room = 804 feet The cost to carpet 1 square foot of the room = 5 dollars. To find the total cost to carpet, we find the area of the room: Area of the room = area of the square = a² Here a = 804 Therefore, the area of the room = 804² = 804 × 804 = 646,416. The cost to carpet the room = 646,416 × 5 = 3,232,080. The total cost = 3,232,080 dollars
To find the cost to carpet the room, multiply the area of the room by the cost to carpet per foot.
So, the total cost is 3,232,080 dollars.
Find the area of a circle whose radius is 804 meters.
The area of the circle = 2,032,932.96 m²
The area of a circle = πr²
Here, r = 804
Therefore, the area of the circle = π × 804² = 3.14 × 804 × 804 = 2,032,932.96 m².
The area of the square is 646,416 cm². Find the perimeter of the square.
The perimeter of the square is
The area of the square = a²
Here, the area is 646,416 cm²
The length of the side is √646,416 = 804
Perimeter of the square = 4a
Here, a = 804
Therefore, the perimeter = 4 × 804 = 3,216.
Find the square of 805.
The square of 805 is 648,025
The square of 805 is multiplying 805 by 805.
So, the square = 805 × 805 = 648,025
