Front

What is the definition of surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies.

Front

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

Back

Total surface area includes all surfaces, while lateral surface area includes only the sides, excluding the top and bottom.
