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


The surface area of a pyramid is 189 cm squared The area of the square base is 49 cm squared. What is the area of one triangular face of the lateral surface?

As stated, the question cannot be answered. The pyramid could be irregular so that its triangular faces have different areas. If it were a regular pyramid, then with a square base it has four triangular faces whose combined area is 189 - 49 = 140 cm2 So each triangular face has an area of 140/4 = 35 cm2

What is the surface area of a square pyramid with base edge 5 m and slant height 10 m?

4x5=20 therfore 20 square metres Each triangular face is 25 sq.m. Therefore the total surface area of the four triangular faces = 100 square metres. If the square base has to be included, add another 25 square metres.
