Unit 6 Lesson 1 Surface Areas of Prisms and Cylinders--

Prism- a polyhedron with two congruent, parallel faces, called bases. Other faces on the prism are called lateral faces

Altitude- perpendicular segment that joins the planes of the bases

Height- the length of the altitude 

Lateral Area- the sum of the areas of the lateral faces

Surface Area- sum of the lateral area and the area of the two bases

Lateral Area of any right prism= ph

Surface Area of any right prism= LA+2B

Cylinder- a solid that has two congruent bases that are circles. The altitude of a cylinder is a perpendicular segment that joins the planes of the bases

Lateral Area of Cylinder= 2PIr*h

Surface Area of Cylinder= LA+2B    or     2PIrH+2PIr^2
