1. The shape of the base is a square. 
2. The lateral faces are triangles. 
3. Including the square and four triangles, the figure has 5 faces. 
4. Square pyramid. 
5. Find the surface area of the square. Find the surface area of one triangle, and multiply by 4 to get all of them. Add the area of the four triangles to the area of the square.
