Prisms

A prism is a solid shape with two identical parallel faces called bases.

The prism is named by the shape of its bases.

Rectangular Prism.  A prism with rectangular bases. Opposite faces are parallel.

6 Faces (each face is a rectangle)

12 Edges

8 Vertices

The surface area of a rectangular prism is the area of the six rectangles that cover it.

Surface Area = 2wl + 2 hl + 2hw

Volume = l w h    (volume=length*width*height)

Only the bases are parallel. 5  Faces

9  Edges

6  vertices

Surface area of a triangular prism = area of the three rectangles + area of two triangles

A formula that works for all prisms is:

Lateral area = perimeter of the base times the height of the prism
