So when I was thinking about it... the sides of a rectangular prism make half of a pyramid, therefore if we combined them together that would give us 1 full pyramid, and then the sides of the rectangular prism make 2 more triangular prisms altogether equalling 3. 

Does my method make any sense to anyone? 

And thanks Jim! I was trying to figure it out on my own,this is how far I've gotten :) lol.
