    The total surface area would be the area of the Triangular bases plus the area of the sides

    The area of a Triangle is A_t=\frac{1}{2}bh

    The area of the side would be the perimeter P_t of the triangle multiplied by the height h_p of the prism.

    So the surface area would be

    S=2A_t+P_t\cdot h_p
