The correct formula to find the surface area of a triangular pyramid is:
Surface Area = (1/2) * base * slant height + (base * height)
Plugging in the values given:
Surface Area = (1/2) * 5 * 6 + (5 * 4.3)
Surface Area = 15 + 21.5
Surface Area = 36.5
Therefore, the surface area of the chocolate pyramid is 36.5 square inches.
