## Visualizing Solid Shapes Class 8 Maths Formulas

• Prism: A prism is a solid, whose side faces are parallelograms and whose ends (or bases) are congruent parallel polygons. A prism has 2 triangular faces, 3 rectangular faces, 6 vertices and 9 edges.
• Pyramid: A pyramid is a polyhedron whose base is a polygon of any number of sides and whose other faces are triangles with a common vertex. A pyramid has 1 square face, 4 triangular faces, 5 vertices and 8 edges.
• Tetrahedron: A pyramid is called a triangular pyramid if its base is a triangle. A triangular pyramid is also called a tetrahedron.
• Plane shapes have two dimensions (measurements) like length and breadth whereas a solid object has three measurements like length, breadth and height (or depth). That is why they are called two-dimensional shapes and three-dimensional shapes, respectively. They are briefly named as 2-D and 3-D figures, respectively. Triangle, rectangle, circle, etc., are 2-D figures, whereas cube, cylinder, cone, sphere, etc., are 3-D figures.
• Views of 3-D Shapes: 3-dimensional objects look different from different positions. So, they can be drawn from different perspectives like top view, front view, side view.
• Mapping Space Around Us: A map is different from a picture. A map depicts the location of a particular object/place in relation to other objects/places. Symbols are used to depict different objects/places. There is no reference or perspective on a map. However, perspective is very important for drawing a picture. Moreover, maps involve a scale which is fixed for a particular map.
• Solids have a fixed shape and occupy a space.
• A solid is made up of polygonal regions, which are called its faces.
• Polyhedron: A solid shape bounded by polygons is called polyhedron (platonic solid).

A polyhedron has some number of plane faces, edges and vertices, which satisfy the relationship: F + V – E = 2,

F stands for the number of faces.

V stands for the number of vertices

and E stands for the number of edges.

The relation F + V – E = 2 is called Euler’s formula.
