The surface area of a triangular pyramid can be found using the formula: Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height). The base area is the area of the triangular base, and the slant height is the height from the apex to the base. The perimeter of the base is the sum of the lengths of all three sides of the triangle.
