SURFACE AREA :-

The space occupied by a two-dimensional flat surface is called the area. It is measured in square units. The area occupied by a three-dimensional object by its outer surface is called surface area. It is also measured in square units.

Generally, Area can be of two types:

(i) Total Surface Area

(ii) Curved Surface Area/Lateral Surface Area

FORMULA:-

Total surface area of cylinder = 2 π r(r+h), where r is the radius of the circular base and h is the height of the cylinder.

SURFACE VOLUME :-

The amount of space, measured in cubic units, that an object or substance occupies is called volume. Two-dimensional doesn’t have volume but has area only. Example, Volume of Circle cannot be found, though Volume of the sphere can be. It is so because a sphere is a three-dimensional shape.

FORMULA :-

Volume of Cuboid = l × b × h.
