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 instinct:
divide Z^2 into 9 equal areas and use 5/9th's of this area to create a five sided cube. then take the remaining 4/9th's of the area and divide those 9ths and so on and so forth.
the end result for this surface area changed to volume is
n=0
4^n(Z^3/3^3)+ 4^(n+1)(Z^3/3^6)+ 4^(n+2)(Z^3/3^9)+...........
and I was fine with that until morning when i realized Z could also = 2*Pi*r and the volume = Pi *( Z/2*Pi)^2 * (2*Pi(Z/2*Pi))
after doing some numerical testing, the values i got were a good bit different.
then in hopes of finding a volume that is closer to my right circular cylinder value i decided to use 4/9 of Z^2 to make my cube
which would give me a volume of
2(Z/3)^3 + 2(Z/9)^3 + 2(Z/27)^3 + ..........
this produced a volume that was closer to my cirrcular cylinder , but not quite?
so how is volume measured? is in in little cubes or not?
are my methods accurate? what is the true max Volume?😕
oh and if at all possible keep this simple so i can undestand...thanks
