**Ms. Sue**, Wednesday, May 14, 2008 at 1:15pmThis is from the above site:

"The lateral area L (area of the vertical sides only) of any right prism is equal to the perimeter of the base times the height of the prism (L = Ph)."

If the perimeter of the base is 10 inches and the height is 3 inches, then the lateral area is 30 inches.

**Reiny**, Wednesday, May 14, 2008 at 3:08pmthe lateral area of a solid is the surface area with the base excluded.

So if it says to find the surface area of a cone you would include the circle, but if you are to find the lateral area of a cone you would find only the top part surface.
