Well, if we fold it into a shape, we find out it's a pentagon prism. Thats as far as I can explain it, but I think that G, C, and A are the answers. I may be wrong though! Heart it if it was helpful! Thanks!
Why is this? Because the base faces are the nonrectangular portions of the pentagonal prism. Think of a room that has 5 sides. The floor and ceiling are both pentagons, so they are the base faces. The five walls are rectangles.
