Prisms

A Prism is a polyhedron with two parallel bases we call faces.

How to find the surface area of a Prism....

you multiply the area of one of the bases by two and add that to the lateral area of the prism

the lateral area is the perpendicular height multiplied by the perimeter of the base

Pyramids

A Pyramid is a polyhedron with 1 base of any polygon and the other faces are triangles that meet at a common vertex

How to find the surface area of a Pyramid....

You add the area of your base to the lateral area of the pyramid

The lateral area of the pyramid is 1/2 of the perimeter of the base multiplied by the slanted height of the pyramid (NOT the perpendicular height)

Cylinders

A Cylinder is two circles connected to a long curved rectangle

How to find the surface area of a Cylinder....

You multiply the area of your base by two and add it to the lateral area

multiply pi by the radius squared and because there are two circles in the shape you multiply it by two. Then you add that to the perpendicular height multiplied by 2 times pi multiplied by the radius

Cones

A Cone is one circle connected to a triangle that is roundish on one side

How to find the surface area of a Cone....

You find area of the base and then add that with the lateral area of the cone

The area of the base is pi multiplied by the radius squared. Then you add that to the slanted height multiplied by pi multiplied by the radius.

Spheres

A Sphere is the set of points equidistant from a center (3-D)

How to find the surface area of a Sphere....

You multiply 4 by pi and that is multiplied by the radius of the sphere squared

Extra Information

kdavis20 — 2014-05-05 12:44:24 UTC

Surface area is the total area of the surface of an object (Surface area can only be measured if the object is 3-D)

A polyhedron is a 3-D object with flat faces in the shapes of polygons

Lateral area is the area of the faces of a shape (that doesn't include the base of the shape)
