What is the difference between total surface area and lateral surface area?

total surface area is all of the area. ex. for a square pyramid it would be the area of the square on the bottom and the four triangle sides lateral surface area is all the surface area EXCEPT the base. ex. for a square pyramid it would be the area of the four sides of the pyramid. the bottom square is NOT included. for a triangular prism it would be the area of the three rectangle sides, NOT the two triangular sides

What is the surface area formula for a triangular pyramid?

The surface area ( S ) of a triangular pyramid (or tetrahedron) can be calculated using the formula ( S = B + \frac{1}{2} P l ), where ( B ) is the area of the triangular base, ( P ) is the perimeter of the base, and ( l ) is the slant height of the triangular faces. Specifically, if the base is an equilateral triangle, the area can be calculated using the formula ( B = \frac{\sqrt{3}}{4} a^2 ), where ( a ) is the length of a side of the base. The surface area will then include the area of the base and the areas of the three triangular faces.
