Performance Standard: 3.4 DOK-2, 3
Knowledge Level: MA 3
A prism has 2 congruent bases and all other sides are lateral faces. Altitude of a prism joins the planes at the bases. The altitude is the true height.
Lateral Area­ sum of the areas of the lateral faces
LA= ph
Surface Area ­ sum of lateral faces plus the area of the 2 bases.
SA = LA + 2B
SA = ph + 2B
Volume ­ V= Bh
