Because that is part of the definition of areas and volumes. You can't have a volume in only one or two dimensions, just as you can't have area in only one dimension.
In order to understand that, lets simplify. Area is 2 dimentional, width and height, while volume is 3 dimentional, width, height, and depth.
Whenever you are answering volume questions, it's always units cubed (^3).
Density = Mass/VolumeVolume is not cubed, although the units in which volume is expressedmay be cubed units.

Yes because volume is measured in cubic units
