Surface Areas and Volumes

Surface Area

Surface area refers to the area of the exposed surface of the three dimensional solid.

There are two types of surface area

(i) Lateral surface area 

(ii) Total surface area

• In general, lateral surface area does not include the base of the shape. 
• Total surface area is the area of the entire object. Lateral surface area (lateral also means side), does not include the area of the top and bottom.

Volume

The volume of any solid refers to the three dimensional space it occupies, often quantified numerically.One dimensional figures, namely lines and two dimensional shapes, namely squares area assigned zero volume in the  three dimensional space.
