Start with a 2D square with a side length of Z. What volume can be made from its surface area? Im not asking for a specific answer, partly because after some experimenting i see that this question is not explicitly answerable in this form.
I realized there are several ways to get several volumes and it all depends on the approach one takes
My first ...[text shortened]... e true max Volume?
oh and if at all possible keep this simple so i can undestand...thanks

That would be a sphere (I think)
As for your little squares, wouldn't you need 6/9 of the little squares to make a closed surface?

Ok so the spherical surface area brings the most volume....I had another person mention that to me when discussing the problem
As for the six surface area's need to make a cube, not sure
the way i look at it there has to be a minimum of 4/9 and a maximum of 6/9
that is what is strange to me for defining volume.....how can 3 different surface areas ...[text shortened]... cube
this all is strange to me....do not all of the gemotrical objects have the same volume?

lastly, as others have said before, the optimal shape for the greatest space enclosed within a minimal surface area (so, for instance, given 100 sq. feet of wrapping paper what's the biggest volume i could wrap up?) is indeed a sphere.

you can clearly make closed geometric objects with different values for area that have the same perimeter. for example, take a 4x4 square (perimeter 16, area 16) and a 2x6 rectangle (perimeter 16, area 12). this includes non-po ...[text shortened]... sq. feet of wrapping paper what's the biggest volume i could wrap up?) is indeed a sphere.

That is a very good question..
It seemed like 4 sides for my cube was the minimum, simply because I had never used a 3 sided cube in any application..there are open boxes and closed boxes and boxes without tops, so thats why i drew the line at 4
altough now I agree, what is really stopping me from taking another side off? its kind of a cool question, ...[text shortened]... e max volume it could contain with the least suface area is
V = 4/3*Pi*(Z/2*sqrt(Pi))^3
