By the Multiplication Method
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 1728.
Step 1: Identify the number. Here, the number is 1728.
Step 2: Multiplying the number by itself, we get, 1728 × 1728 = 2,985,984.
The square of 1728 is 2,985,984.
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 1728.
So: 1728² = 1728 × 1728 = 2,985,984
By Using a Calculator

Solved Examples on Square of 1728
Problem 1
Find the length of the square, where the area of the square is 2,985,984 cm².
The area of a square = a²
So, the area of a square = 2,985,984 cm²
So, the length = √2,985,984 = 1728.
The length of each side = 1728 cm
Explanation
The length of a square is 1728 cm.
Because the area is 2,985,984 cm² the length is √2,985,984 = 1728.
Problem 2
Emma is planning to paint her square garden wall of length 1728 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 1728 feet
The cost to paint 1 square foot of wall = 3 dollars.
To find the total cost to paint, we find the area of the wall.
Area of the wall = area of the square = a²
Here a = 1728
Therefore, the area of the wall = 1728² = 1728 × 1728 = 2,985,984.
The cost to paint the wall = 2,985,984 × 3 = 8,957,952.
The total cost = 8,957,952 dollars.
Explanation
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 8,957,952 dollars.
Problem 3
Find the area of a circle whose radius is 1728 meters.
The area of the circle = 9,380,531.84 m²
Explanation
The area of a circle = πr²
Here, r = 1728
Therefore, the area of the circle = π × 1728² = 3.14 × 1728 × 1728 = 9,380,531.84 m².
Problem 4
The area of the square is 2,985,984 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 2,985,984 cm²
The length of the side is √2,985,984 = 1728
Perimeter of the square = 4a
Here, a = 1728
Therefore, the perimeter = 4 × 1728 = 6,912.
Problem 5
Find the square of 1729.
The square of 1729 is 2,992,641
Explanation
The square of 1729 is multiplying 1729 by 1729.
So, the square = 1729 × 1729 = 2,992,641
