Let's start with the Surface area and volume.
Area
The space occupied by a two-dimensional flat surface. It is measured in square units.
Generally, Area can be of two types
(i) Total Surface Area
(ii) Curved Surface Area
Total surface area
Total surface area refers to the area including the base(s) and the curved part.
Curved surface area (lateral surface area)
This refers to the area of only the curved part excluding its base(s).
Surface area: The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Volume
The amount of space, measured in cubic units, that an object or substance occupies. Some shapes are two-dimensional, so it doesn’t have volumes. For example, the Volume of Circle cannot be found, though the Volume of the sphere can be. It is so because a sphere is a three-dimensional shape.
Volume: Volume is the quantity of three-dimensional space enclosed by closed surface i.e the space that a substance or shape occupies or contains. The SI unit of volume is ‘cubic meter’.
Cube Shape
A solid having its length, breadth, height all to be equal in measurement is called a cube.
A cube is a solid bounded by six square plane regions, where the side of the cube is called edge.
Cuboid Shape
A cuboid is a closed 3-dimensional geometrical figure bounded by six rectangular plane regions.
