Origami Related Math Question

[josh_the_hot_boy]

Okay so I created Bucky Ball its a sphere anyways its 7" in diameter and took 30 paper units to make. My question is I have another model I designed (but haven't yet built) also a Bucky Ball similar design but this time its 16,000 paper units. I want to figure out how big in diameter it might be. See I thought to do it like this the smaller one is 7" and 30 units so 16,000 units X 7" divided 30 units which gives me 3733" roughly. Does that sound right to you??? can I use that type of math since they are both basically the same just one has more pieces???

This is the 7" ball I made for reference.


Well I hope this isn't to confusing. Any help would be great.

Thanks Joshua.

MMmmm... interesting question Josh.:thinking:

I'm not guaranteeing my logic is correct but...I'm presuming the units are to be the same size?... if so then the surface area of the larger sphere is going to be about 533 times that of the smaller 16000/30...and the formula surface area of a sphere = 4 x pi x r2

so the small one is 4 x 3.142 x 3.5 x 3.5 = 154 sq in and scaling up to 533 times larger gives 82,082... so working the formula in reverse I reckon it should be somewhere around 81 inch radius... in other words about 13.5 feet across!!

I'm totally confused

Jim, your reply is quite amazing , I can't even add anything sarcastic )

 

[josh_the_hot_boy]

Yes the pieces are the same size I figured I could just do like this.



So like A is 16,000 units and C is 30 units and D is 7 IN. So like 16,000 X 7 Divided by 30 So B is 3733

Idk maybe that is wrong Slim Jims 13.5 Ft seem good.

I have always troubles with inches. But the logic of your calculation is absolute right Jim.

i was told there would be no math questions today:?:worried:

Are you using enough lube?

Naughty thoughts lube my mind.

I grabbed my calculator and googled for some formulas and I came to the same conclusion as slimjim. Maybe you can give us the instructions how to build one so I can fold my own "josh the hot ball"

Part 1 from Tom Hull who invented the unit.





He explains how to make the unit and assemble them all together.

It takes 30 squares of paper to make the model I made above. 3-4 IN squares in size are needed nothing bigger.

I can't believe this question was asked on a gay forum specialising in porn!

Anyway, I can't be bothered doing the calculation right now, but roughly speaking the diameter is proportional to the square root of the surface area, which is simply the number of little paper pieces you used. Not exactly proportional, because they are not exactly the same shape - the big one will be more nearly spherical than the small one, but near enough.

I think this is consistent with what slimjim said.

I used to make lots of paper models of this kind when I was in my teens. Not Buckyballs though, mostly convex polyhedra with no holes.

Why are you surprised? It's exactly what this section is here for.

Well OZ, this is the general discussion area, so I guess any question is poseable.
