Maths question

[Four Cofffee]

According to Wiki a 40mm diameter table tennis ball has a volume of 33510 cubic mm, how big would a ball be which had 200,000 times that volume?

[hyperblue]

200,000 times bigger.

[HOGEPH]

Too big to use down the local sports club.

I make it 2339.2mm diameter or 58.4 times bigger (in diameter) with a quick bit of calculator bashing, any one wanna clarify that?

You'll need a bigger bat.

If you multiply 58.4 x 58.4 x 58.4 what answer do you get?

er, the wrong one !!!!


(ok, ok, it's a cube law between volume and diameter!)

A table tennis ball that even I could hit?

Just out of interest, why 200,000 times bigger?

Just a fact I am looking to illustrate.

If the conscious brain processes a ping pong ball sized amount of data per second, the unconscious brain processes a ball almost 8 feet across ( x200,000).

I now need to buy some ping pong balls to take with me, and an 8 foot one.
