6.3- Prisms

7.1 – Surface Area and Volume Formulas

7.2 – Surface Area & Volume of Prisms

7.3 – Surface Area & Volume of Pyramids

A crash course in:

Parts of a polyhedra:facesedges

vertices

Remember from last time

Today, we’re going to talk about specific polyhedra called:

Prisms

and

Pyramids

FACES can be eitherBases

Lateral Faces

PRISMS

*have 2 bases: they are || and

*Lateral faces are ALWAYS rectangles or parallelograms

PYRAMIDS*have 1 base.

*Lateral faces are ALWAYS triangles

Naming Prisms and PyramidsThey 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

Surface Area

The number of

square units on the surface of a shape.

units2

VolumeThe number of

cubic units inside a shape.

units3

You should have a paper that lists all the formulas for surface area and volume for various shapes.
