Apologies if this question is too much high school maths for the site, I'm a refugee from the webmaster stack site, and thought I might find some help here.
The question concerns candle making (in the real world). I'm thinking of purchasing some large pillar candle moulds from a company in Australia (can't find the right size anywhere else) and I need to check that I can melt enough wax to fill a single mould in one go and if not figure out what size boiler I should buy.
Problem is wax is sold in dry weights and the volume is calculated in, well, liquid volume. I don't know how to translate between the two.
- Volume is V = πr2h.
- Mould is 100mm diameter and 241mm tall
- = 7574285.714285708 Cubic millimeters
- = 7.574285714 cubic liters.
So, the problems are these:
- Basically the result doesn't make complete sense to me - it shouldn't be that large! Have I done the conversion incorrectly or is there a difference that I'm unaware of between American and British volume calculations (I'm a Brit).
- Candle wax is sold in dry kilograms, I've seen various conversion charts online, but they often seem to be guess work. Is there a simple formula for converting a dry weight of a solid into it's resulting liquid volume.
Apologies if this is too simple or the solution is obvious, and thanks in advance for your help.
