Scale Conversion Help !

[Captain Canada]

Is anybody here a Mathmologist ? I said is anybody here a Mathmologist ?!

I've got a 48th scale centreline tank from a Phantom on a 72nd scale bird.

Let's say it hold 1400 litres in 48th scale.....what would that equate to in 72nd ? 2200 ? Is that a good guess ? There must be an eas way to figure it out, what with those scientific caliculators ya'll got and such..........

There must be an eas way to figure it out, ...

There is.

But I'm on my fourth glass of wine.    

[Captain Canada]

.....carry the four

[John Howling Mouse]

Um, how many litres in Ratty's wine bottle?

You ever have one of those things when you can see the mathematical formula conceptually, but the actual execution is just right outside the edge of your mind's eye?  I'm having one of those moments right now.  Lemme get back to you on that tomorrow.

Since we are dealing with volume, it would be the cube of the ratio.  

Since the ratio of the two scales is 72 / 48, we are looking at
(72 / 48 ) ^ 3 * 1400.

(1.5) ^ 3 * 1400

3.375 * 1400

4725 liters.

So....I'm guessing I times (x) the actual number of litres of the frop tank ny 3.375 ? If that's the case....thanks !
