Okay, a rectangular pyramid is just a square and four triangles of equal size, right? So the area of the square is...
base * base
The triangles are one half base times height...
1/2 * base * height
And there are four of them, which means their combined area is...
2 * base * height
Add those to the square, and you get the surface area:
(2 * base * height) + (base * base)

There are rectangular pyramids and prisms. The area of a prism is length time width times height. I forget the pyramid formula.

Side times side = area. Side times side times height, the product divided by two = volume.
