4. Each base of a triangular prism has an area of
   43 square centimeters. Each lateral face has
   an area of 25 square centimeters. What is the
   surface area of the prism?

To find the surface area of the triangular prism, you need to add the areas of the two triangular bases and the three rectangular lateral faces. Since each base has an area of 43 square centimeters, the total area for the bases is square centimeters. The total area of the three lateral faces is square centimeters. Therefore, the total surface area of the prism is square centimeters.

So, the surface area of the prism is 161 square centimeters!
