What are the different terms in solid mensuration?

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.
