Explanation:

"A composite solid made up of prisms" is like a cube stacked on top of a box or a little house shape that is a box for the building and a pyramid for a roof. These are just examples, possibilities. The surface area of the whole thing would be the surface area of each piece added together. But then you would have to subtract the sides that aren't showing, such as the top of the box and the bottom of the pyramid in the building+roof (box+pyramid) example.
