Formulas of Surface area and Volume

So hi guys my name is Sumeet and you are welcome in Blog .

In this blog you will be seeing the formulas for finding area volume and sides of figures like Square trapezium and etc.

Square

Perimeter of Square : 4 x sides

Area of square : side x side

Total Surface area of Square : 6 x (side x side) 

Lateral surface area of Square or area of four walls : 4 x (side x side)

Volume of Square : side x side x side 

Diagonal of square : side  x root 2 

Sides of Square : Perimeter/4

Rectangle

Perimeter of Rectangle : 2(L+B)

Area of Rectangle : L x B

Total Surface area of Rectangle :  2(L+B X B+H X L+H)

Lateral surface area of Rectangle : 2 H (L+B)

Volume of Rectangle : L x B x H

Diagonal of Rectangle : In root L square + B square 

  

Parallelogram

Area of any parallelogram when Height is Given is :

Base x Height

Rhombus

Area of Rhombus = 1/2(The product of diagonals)

The Perimeter :  4 x side 

Trapezium

Area of is trapezium : 1/2(Sum of parallel sides) x (Distance between parallel sides)

Circle

Circumference of circle : 2 pie x r

Radius : diameter/2;

Diameter : 2 x r 

Area : pie x r x r 

When there are two radius : pie(R x R - r x r)

Volume Of circle : 4/3 pie r x r x r

Volume of Hemisphere : 2/3 pie r x r x r

And That's all for this blog ,

In the next Blog I will be publishing a Very esay method to learn Trignometric values .
