## AREA AND PERIMETER FORMULA FOR ALL SHAPES

On the webpage "area and perimeter formula for all shapes" we are going to see formula for each and every shapes in math.

What is perimeter?

The continuous line forming the boundary of a closed geometrical figure.

What is area?

The extent or measurement of a surface or piece of land.

AREA AND PERIMETER OF SQUARE

Area of square = a²

Perimeter of square = 4a

here "a" stands for side length of square.

Examples problems on perimeter of square

Next we are going to see a formula for the next shape rectangle of the topic "area and perimeter formula for all shapes"

AREA AND PERIMETER OF RECTANGLE

## AREA AND VOLUME OF CUBE

Curved surface area of cube = 4a²

Total surface area = 6a²

Volume of cube = a³

## AREA AND VOLUME OF CUBOID

Curved surface area of cube = 2h (L + b)

Total surface area = 2(Lb + bh + hL)

Volume of cuboid = L x b x h

Here "L" "b" and "h" stands for length,breadth and height respectively.

## AREA AND VOLUME OF CYLINDER

Curved surface area = 2 Π r h

Total surface area = 2 Π r (h + r)

Volume = Π r² h

Examples problems of cylinder

## AREA AND VOLUME OF HOLLOW CYLINDER

Curved surface area= 2Π h (R+r)

Total surface area =  2 Π (R + r) (R - r + h)

Volume = Π h (R² - r²)
