1. A crash course in:
6.3- Prisms – Surface Area and Volume Formulas – Surface Area & Volume of Prisms 7.3 – Surface Area & Volume of Pyramids

2. Parts of a polyhedra: faces edges vertices
Remember from last time
Today, we’re going to talk about specific polyhedra called:
Prisms
and
Pyramids

3. Bases
Lateral Faces
FACES can be either

4. PRISMS PYRAMIDS *have 1 base. *have 2 bases: they are || and 
*Lateral faces are ALWAYS triangles
*have 2 bases: they are || and 
*Lateral faces are ALWAYS rectangles or parallelograms

5. Naming Prisms and Pyramids
They have 3 names – just like most of you
First name:
RIGHT – straight up and down – all lateral sides are rectangles or
OBLIQUE – at least one lateral side is a parallelogram (slanted)
Middle name:
Names the shape of the base:
“triangular”
“rectangular”
“octagonal”
“trapezoidal”
“hexagonal”
Last name:
Names the family:
Prism Or
Pyramid

6. Volume Surface Area The number of cubic units inside a shape. units3
The number of square units on the surface of a shape.
units2
You should have a paper that lists all the formulas for surface area and volume for various shapes.
