What is the Square of 216
The square of a number is the product of the number itself.
The square of 216 is 216 × 216.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 216², where 216 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 216 is 216 × 216 = 46,656.
Square of 216 in exponential form: 216²
Square of 216 in arithmetic form: 216 × 216
How to Calculate the Value of Square of 216
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.
- By Multiplication Method
- Using a Formula
- Using a Calculator
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 216.
Step 1: Identify the number. Here, the number is 216.
Step 2: Multiplying the number by itself, we get, 216 × 216 = 46,656.
The square of 216 is 46,656.
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 216.
So: 216² = 216 × 216 = 46,656
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 216.

Solved Examples on Square of 216
Problem 1
Find the length of a square where the area of the square is 46,656 cm².
The area of a square = a² So, the area of a square = 46,656 cm² So, the length = √46,656 = 216. The length of each side = 216 cm
Explanation
The length of a square is 216 cm.
Because the area is 46,656 cm², the length is √46,656 = 216.
Problem 2
A rectangular garden has a length of 216 meters and a width of 100 meters. Calculate the area of the garden.
The length of the garden = 216 meters The width of the garden = 100 meters Area of the garden = length × width Area = 216 × 100 = 21,600 square meters
Explanation
To find the area of a rectangle, multiply the length by the width.
So, the area of the garden is 21,600 square meters.
Problem 3
Find the area of a circle whose radius is 216 meters.
The area of the circle = 146,778.24 m²
Explanation
The area of a circle = πr²
Here, r = 216
Therefore, the area of the circle = π × 216² = 3.14 × 216 × 216 = 146,778.24 m².
Problem 4
The area of a square is 46,656 cm². Find the perimeter of the square.
The perimeter of the square is 864 cm.
Explanation
The area of the square = a²
Here, the area is 46,656 cm²
The length of the side is √46,656 = 216
Perimeter of the square = 4a
Here, a = 216
Therefore, the perimeter = 4 × 216 = 864 cm.
Problem 5
Find the square of 217.
The square of 217 is 47,089.
Explanation
The square of 217 is multiplying 217 by 217.
So, the square = 217 × 217 = 47,089
