I' trying it now. I just thought I’d mention that I think you can make a regular icosahedron (http://en.wikipedia.org/wiki/Icosahedron) from the triangular units. I’ trying it now.

(Thanks for mentioning the archives -- I tend to forget them.) But it's evident from the pictures I can see that this is where he was tending. But I have a way of doing the volume without recourse to that unpleasant integration business. Just need to grok some more Archimedes, first.

It kinda seems like comparing apples and oranges to me. The people working on this problem were trying to inflate a teabag (two square pieces of paper put on top of each other with the edges glued together) to find the maximum volume it can contain. I seem to recall reading about such research suggesting a 3D form similar to (or exactly the same as?) your pillow box as an approximation to the solution. But these people were not looking to fold such an object from a single square of paper, so I would doubt that they did that. Andrew Kepert seems to be an Assistant Dean or somesuch now at Univ. Newcastle (AU): http://www.newcastle.edu.au/school/math-physical-science/our_staff/kepert_andrew.html And his teabag web page is now down, but you can look it up: http://frey.newcastle.edu.au/~andrew/teabag/ on the Internet Wayback Machine: http://web.archive.org/web/*/http://frey.newcastle.edu.au/~andrew/teabag/ and take a peek at it (although not all of the pictures work).
