How many square feet are in an area in witch the volume is 333513.4 cubic inches.
There aren't 'square feet' (an AREA) in 'Cubic Feet' (a VOLUME) ...they are two different things.
When you multiply AREA times HEIGHT you get VOLUME.
Given this volume of 333513.4 the AREA (i.e. footprint) of the volume can be just about ANY value which you can only calculate if you know the third dimension (height)
