You need to specify which of the dimensions apply to which parts of triangular prism. You only need 4 dimensions: the sides of the triangular base and the height of the triangular prism. The surface area would be perimeter of the triangle * height of the prism + 2 * area of the triangle. You can use Heron's formula to find the area of the triangular base when it is not equilateral.
