Why would we measure volume in cubic units?Please explain why perimeter is measured in units and area is measured in square units. Please give...

The perimeter is a length. Length is measured in terms of
appropriate units like meters, inches, etc.


Area is a
product of 2 lengths. For example the area of a rectangle is the product of the length
of its sides, the area of a triangle is also the product of two lengths which in this
case are the length of the base and the length of the height. As a result of this area
is expressed in square units, like square meters, square inches,
etc.


Volume is a product of 3 lengths. For example the
volume of a cuboid with sides w, l and h is w*l*h, the volume of a sphere is
(4/3)*pi*r^3, etc. As a result volume is measured in cubic units, like cubic meters,
cubic inches, etc.
