## How to Calculate Square 1 to 30?

There are **2 methods** mentioned below for calculating the values of squares of numbers ranging from 1 to 30.

### Method 1- Multiplication by itself

Under this method, the value of the square is solved **by the multiplication of a given number by itself**. For example, the value of square of 6 = 6 × 6 = 36. Here, the final product 36 tells that it is the square of the number 6. This method is generally applied to smaller numbers.

### Method 2- Applying basic Algebraic Formulas

Under this method, a given number n is first written as (a+b) or (a-b), where ‘a’ is a multiple of 10 and ‘b' refers to any value less than 10. After that, the fundamental algebraic formula is applied to calculate the value of squares of the given number. In this method, the 2 basic algebraic identities formulas can be applied to find the value of squares of a number. **(a + b)² = a² + b² + 2ab or (a - b)² = a² + b² - 2ab**. This method is preferred where b has a smaller value. For example, for finding the square of 28, we can write it as (20+8) as option 1 or (30-2) as option 2.

Next, we need to apply the basic algebraic formula and then we have,

Option 1: [20² + 8² + (2 × 20 × 8)] or Option 2: [30² + 2² - (2 × 30 × 2)]

After expanding the expressions further,

we get Option 1: (400 + 64 + 320) = 784 or Option 2: (900 + 4 - 120) = 784.

## Square 1 to 30 Solved Questions

**Question 1: When a circular plate has a radius of 8 inches. Calculate the area of the plate in sq. inches.**

**Solution:** Area of the circular plate (A) = πr² = π (8)²

By putting the value of the square of 8 from Square 1 to 30 chart;

i.e. A = 64π

Hence, the area of the circular plate = 201.14 inches².

**Question 2: Calculate the area of a square carpet whose side is 5 inches.**

**Solution:** Area of square carpet (A) = Side²

i.e. A = 5² = 25

Hence, the area of a square carpet is 25 inches².

**Question 3: Two square-shaped books have sides of 6m and 8m respectively. Calculate the combined area of both books.**

**Solution:** Area of book = (side)²

⇒ Area of 1st book = 6² = 36 m²

⇒ Area of 2nd book = 8² = 64 m²

Hence, the combined area of both the books is 36 + 64 = 100 m²

**Question 4: Calculate the addition of the first 10 odd numbers.**

**Solution:** The addition of the first n odd numbers is expressed as n²

⇒ Addition of first 10 odd numbers (n) = 10²

By putting the value of the square of 10 from squares 1 to 30 chart,

The sum of the first 10 odd numbers = 100

**Question 5: Find the total surface area of a spherical ball that has a radius of 5 cm.**

**Solution:** As we know the total surface area of a sphere (A) = 4π r² square units.

A = 4π( 5) ² cm²

A = 100 π cm² = 314 cm²
