SURFACE AREAS AND VOLUMES

  1. Surface Area of a Cuboid and a Cube
  2. Surface Area of a Right Circular Cylinder
  3. Surface Area of a Right Circular Cone
  4. Surface Area of a Sphere
  5. Volume of a Cuboid
  6. Volume of a Cylinder
  7. Volume of a Right Circular Cone
  8. Volume of a Sphere

Cuboid – with length , breadth  and height

Perimeter of Cuboid =

Length of diagonal =

Lateral surface area =

Total surface area =

Volume =

Cube – with side

Perimeter of cube = 12 x edge

Lateral surface area =

Total surface area =

Volume =

Right Prism

Lateral Surface area = Perimeter of base x Height

Total surface area = Lateral Surface area + 2(Area of one end)

Volume = Area of base x Height

Right Circular Cylinder – with radius  and height

Curved Surface area =

Total surface area =

Volume = 

Hollow Cylinder

Each base surface area =

Curved surface area =

Total surface area =

Volume =

Right Pyramid

Lateral Surface area =  x Perimeter of base x Slant Height

Total surface area = Lateral Surface area + Area of base

Volume =  x Area of base x Height

Right Circular Cone – with with radius , height  and slant height

A right circular cone is a solid generated by revolving a line segment which passes through a fixed point and which makes a constant angle with a fixed line. The fixed point is called the vertex of the cone, the fixed line is called the axis of the cone.

Curved Surface area =

Total surface area =

Volume = 

Volume =  x Area of the base x height

Sphere (Solid) – with radius

The set of all points in space which are equidistant from a fixed point is called a sphere. The fixed point is called the centre of the sphere and the constant distance is called its radius.

Curved Surface Area =

Total surface area =

Volume =

Hemisphere – with radius

Curved Surface Area =

Total surface area =

Volume =

Spherical shell – with inner with radius  and outer radius R

Volume =
