Vsphere  =(4/3)pi *(d/2)^3   = (4/3)pi * (8.6 / 2)^3  =   about 333 in^3   [to the nearest tenth]

LOLOLOL!!!!!

 

Good point......we'll consider it "pre-drilled".........only because I couldn't find any "finger hole" formulas to reduce the volume.......

 

 

I may see if Sir LA-Tex knows  of any such formulae........he's pretty good at researching the obscure........!!!!

 

Stay tuned.......

The holes are near enough to cylinders so the formula is easy.

Here is a video that gives you the dimensions AND shows you how to drill the holes.

PLUS it is in imperial measurments so you lovely US people should be right at home :))

Thanks for that video, Melody........

 

Unfortunately.........Sir La-Tex    doesn't fully grasp "imperial" measurements......

 

He deals easily with "imperial minims,"  however........

 

Also.....the problem with trying to ascertain  a good estimate for "thumb and finger hole volume" is that this is equivalent to trying to determine how much of a pie is displaced by having one's thumb and fingers in it..........

 

Thus, there is probably some other  "pie" component to our spherical volume estimation.......

Yes CPhill,  You have made many very good observations here.

You know, fingers in pies is something I expect Sir Phill La-Tex is quite familiar with.

Chimps so like to put their fingers in their pies ..........

I wonder how that formula might go.

 

\(V=\displaystyle \int_0 ^{chimp\; digit\;l ength}\left(\pi r^2h-6\frac{\delta\pi}{\delta r}\right)dh\)

 

I had to subtract the 6 partial pies because Sir La-Tex had 5 of his friends over.

There was Lancelotlink, .....   I can't remember who the others were.  

There was that brilliant female one, I have forgotten her name.....    

Anyway, all chimps look the same to me.     indecision
