This is a triangular prism.
The lateral faces are triangles; this means that the two bases are parallel to one another.  This makes it a prism instead of a pyramid.
The bases being triangles makes it a triangular prism.

D because the top and the bottom are faces and the middle is a face
        
                    
             
        
        
        
To answer you need to isolate T so you add 19 to both sides. so T = 36
Hope that helped! If you don't get it message me and I can try to re explain :)
