Aim: How do we identify solids ?

    Solid Geometry: Solid geometry is the geometry of 3-dimensional space.

Properties:

• Volume
• Surface Area

Two Main types of solid:

1. Polyhedra
2. Non-Polyhedra

Polyhedra: Flat Surface

• Prism                       
• Pyramids
• Platonic solids

Non-Polyhedra: If any surface is not flat

• Sphere
• Torus
• Cylinder
• Cone

Prisms: Has the same cross section all along its length
Cross sections: The shape you get when you cut straight down
Surface Area: The area of the bases + the Lateral Area ( area of the side)
