~ To be able to use a formula to find the surface area of a right prism ~To be able to use a formula to find the volume of a right prism ~ To be able to use Cavalieri’s Princaple to make a formula for a Oblique Prism
 * Objectives-

Vocab-
 * -* Altitude- Is the perpendicular distance form the vertex to the opposite side of the vertex; is the line through the vertex of a perpendicular figure to the base


 * -* height- Is the distance from the top of a figure to the bottom of the figure

~Formulas~ Surface Area of a Right Prism: + S=L+2B Volume of a right prism: + V=BH

-_-Cavalier’s Principle -_- Both solids have equal volumes if the bases of both solids are equal and if the equal heights and cross sections that are formed by every plane parallell

=7.3= Vocab- 1.) Pyramid- a figure that has a polygonal base with triangular faces that meet in a common place 2.) Base- is the surface forming part of a figure that is most nearly horizontal or where the figure stands 3.) Lateral Faces- 4.) Vertex of a Pyrammid- 5.) Base Edge- 6.) Lateral Edge- 7.) Regular Pyramid- 8.) Slant Edges-
