Pack manufacturers usually specify the volume, height, width and depth of a pack. The volume is expected to be significantly less than the product of the height, width and depth since the packs have rounded corners.
Is it safe to assume that a fully loaded pack will be no higher than its specified height, no wider than its specified width, and no deeper than its specified depth? If not, what is the meaning of these specifications??
What got me started on this question is my interest in the Aarn Peak Aspiration pack. The Aarn web site lists (for the long option) the following dimensions:
The product of these dimensions (6.5 * 3.4 * 2) is 44.2 l. The Aarn web site specifies the volume as 50 l. As far as I can see, this means that one or more of the dimensions must be incorrect - the volume can certainly be less than the product of the height*width*depth, but it is impossible for the volume to be more than that!
Am I missing something here, or is this simply an error on the Aarn web site?
