=GRCA625 Chapter 9 Link= =7.1 Surface Area and Volume=

Objectives:

 * Find out about ratios of surface area to volumes.
 * Concepts of maximizing volume and minimizing surface area.

Surface Area and Volume Formula:
Surface Area = S Volume = V Length = L Width is W, and H is height

S = 2LW+2LH AND V = LWH
=7.2 Surface Area and Volume of Prisms=

Objectives:

 * Use the formula for finding the surface area and volume of a right prism.
 * Use Cavalier's Principle.

Volume of a prism:V=Bh Cavalieri's Principle:
If two solids have equal heights and the cross sections formed by every plane parallel to the bases of both solids have equal areas, then the two solids have equal volumes. =7.3 Surface Area and Volume of Pyramids=

Objectives:
[|]
 * Define and use a formula for the surface area and volume of a pyramid.

Volume of a Pyramid: V=1/3Bh
= = =7.4 Surface Area and Volume of Cylinders=


 * Define and use a formula for the surface area and volume of a cylinder.

Cylinder: a solid that has two circular bases with a lateral surface conecting them.
Surface area: S = L+2B Volume: V = Bh
