Recall:
Volume
A one dimension quantity − length
and it is represented as
Two dimension quantity − length
and breadth. Which can be represented as
The space ocupied here: 1cm x 1cm
= 1 cm2.
Two dimensional quantity is
called as Area.
Definition of
volume
When we expand 1 cm from the surface of 2D, it
forms 3D.
The space occupied here: 1cm x 1cm x 1cm = 1 cm3.
