### 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.

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?

Formula for what? The volume? The area?

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
