There are different formulas for different figures ... also, areas are of two types . They are surface area and lateral s.a.

The sum of all the areas of a surface of a solid is called the 'surface area'.

Sum of the surface areas or each of its seven faces. Only the two pentagonal bases should have equal areas; there is no need for any of the other faces to have equal areas.

It is the total surface area.

It will require many pages of a text-book to show the area- formulae for all figures.

The surface area of the 3-D figure will be the total of the areas of the 2-D figures.

Surface Area is the sum of the areas of the surfaces in the figure. Surface Area of a Prism= 2lw+2lh+2wh Surface Area of a Cylinder= 2(3.14)r(r)+2(3.14)rh

1. Plane Figures- A flat, closed figure that is in a plane- A plane figure can be made of straight lines, curved lines, or both straight and curved lines.2. Solid Figures- The figures which occupy space are called solids.- Solids are three dimensional figures i.e., they have length, breadth & height.- There are two important facts related to solids-a. Every solid has a surface area. Some solids have plane surfaces, others have curved surfaces.b. Every solid has a 'bulk' & its bulk occupies some space.3. Surface area-It is the sum of areas of all visible (exposed) surfaces of a solid.4. Volume-It is the three dimensional space occupied by a solid, liquid or gas.5. Lateral surface area - is the sum of the surface areas of all its faces excluding the base.6. Total surface area - is the sum of the surface areas of all its faces including the base.
