Geometry: Introduction - Surface Area and Volume
This is a free lesson from our course in Geometry
 
   
You have explored so far two dimensional shapes i.e. having only length and breadth like polygons, circles etc. are planar shapes. However, the experience in the real world reveals that every object has three dimensions i.e. length, breadth, height and occupy space. Such objects which occupy space are called solids. To have deeper understanding, E.g. a brick used in construction, which can not be contained in a single plane and it has dimensions like- length 10 in, breadth 5 in and height 4 in or so. Therefore, no single plane can contain such it in totality. Other examples, having the common 3D shapes with which you should be familiar are: cubes, prism, cylinder, pyramid etc. Apart from important properties of such objects, method to calculate their surface area and volume are also covered in this chapter.

This lesson explains using Video the important properties and relationships that should help you to solve the problems and help in doing Geometry homework.
