Two students find the surface area, S. A., of this regular hexagonal prism. One student multiplies the perimeter of the hexagon by the height of the prism to find the lateral area, L. A. The other student finds the area of each lateral face then multiplies by the number of faces. What is the L. A.? The S. A.? Use pencil and paper. Explain why both approaches lead to the same S. A.
