Find the surface area of the triangular prism.  The base of the prism is an isosceles triangle.

First of all, the two large rectangles at the side have sidelengths of 48 and 25. The total area of these are 2400cm^2. The front and back triangle have 2*1/2*14*24=336cm^2. Finally, the bottom face has area 14*48=672cm^2. 

 

We sum these together to get 3408cm^2.
