Cryptography!Somereminders: Surface Area of a Prism o  SA = 2B + LA SA is surface area

B is the area of the base LA is the lateral area LA = ph p is the perimeter of the base h is the distance between the bases

Base of a Wigure is how you name the Wigure: Rectangular prism (base is a rectangle) Pentagonal prism (base is a pentagon)

Activity34–PrismsandCylinders

Surface Area of a Cylinder o  SA = 2B + LA SA is surface area

B = πr2 LA = 2πrh

o  SA = 2πr2 + 2πrh r is the radius of the circle

h is the distance between the bases

Activity34–PrismsandCylinders

Practice: Find the surface area of the cylinder.

Activity34–PrismsandCylinders

Go back through the Cryptography problems and solve for the volume of the prisms. I wrote my volume in a different color to remind me of the difference. J
