text: # SSC Higher Mathematics Note 13th Chapter Solid Geometry
  
  SSC Higher Mathematics Note 13th Chapter Solid Geometry. Solids of different shapes are always needed and used in our practical life. Among these, there are regular and irregular solids. The method of determining volumes and areas of surfaces of regular solids and compound solids constructed of two regular solids will be discussed in this chapter.
  
  Plane surface: If the straight line joining any two points on a surface lies wholly on that surface, then the surface is called a plane surface or simply a plane. The upper surface of the still water of a pond is a plane. The smooth floor of a room polished with cement or mosaic is considered to be a plane. But geometrically it is not a plane, for there are high and low points on the floor.

  A prism is a polyhedron, bounded by two parallel polygonal faces and the other faces always being parallelograms. The parallel sides are known as bases and the sides are known as lateral faces. If all the lateral surfaces are rectangular it is called a right prism;  otherwise, they are called obliques prism.  Practically right prisms are frequently used. The prism is named after the shape of its base. For example, triangular prism, quadrilateral prism, pentagonal prism, etc.
  
  teachingbd24.com is such a website where you will get all kinds of necessary information regarding educational notes, suggestions and question patterns of schools, colleges, and madrasas. Particularly, you will get here special notes of physics that will be immensely useful to both students and teachers. The builder of the website is Mr. Md. Shah Jamal who has been serving for 33 years as an Assistant Professor of Physics at BAF Shaheen College Dhaka. He expects that this website will meet up all the needs of Bengali version learners /students. He has requested concerned students and teachers to spread this website home and abroad.
