Total Surface Area and Lateral Surface Area

Front

What is the definition of Total Surface Area?

Back

Total Surface Area is the sum of the areas of all the faces (including bases) of a three-dimensional shape.

Front

What is the definition of Lateral Surface Area?

Back

Lateral Surface Area is the sum of the areas of all the faces of a three-dimensional shape, excluding the bases.
