Volume and surface area for rectangular based pyramids

i know this may sound a little stupid, but if anybody could help me by giving formulas for the volume and surface area of a rectangular based pyramid it would be greatly appreciated.

Re: Volume and surface area for rectangular based pyramids

The general formula for the volume of a pyramid is:

where b is base and h is height.
In the case of rectangular pyramids, the base is equal to the length multiplied by width.

The surface area for the rectangular pyramid is:

where l is length, w is width, and s is the, umm, height of the triangle?

Re: Volume and surface area for rectangular based pyramids

Formula for what? The volume? The area?


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
