I need your huge brain:
I'm trying to help the partner with some calculations at work, but we've got ourselves all confused and argumentative.
Basically we are trying to work out the wieght of something given only the dimensions.
It's glass, solid glass.
the formula partner was using was:
At the moment the length * height * number of sheets of glass = square metres. It is then divided by a preset amount based on the substance (width) of the glass to give us tonnes.
which i make as
(L * H * n) / W = tonnes
I was saying it should be
(L * H * W) * n = Volume
but i can't finish the step to turn that into wieght. I think i need to know the denisty.Please can you (or anyone) tell me the formula to convert volume into wieght.
(yes i've tried using google)

and you're right about the volume
what sort of glass is it? I have resources.

for pure SiO2 in a few minutes, but most glass has impurities in it.
heavy ones.
Like calcium

i'm going to the fridge - i'll be back with processed cheese slices and beer

we use memsnet a lot...it isn't the best, but it's easy to find

including low iron for solar panels.
I dodn't think it matters given the amounts they are caluclating.
The only one i knoe they fudge the fuigures with) is the glass with the wire in it which wieghs a lot more.
an average for a nice pure glass will be lovley thanks (and do i dived or mulply the volume by the denisity?)

density is kg/m^3 so you multiply times the density to cancel the m^3. just make sure your units are right.
2200 kg/m^3 seems to be about right

We need to know
A) what dimensions you have already
B) what dimension you're trying to find
This may help, not sure what you're after.
Pulling numbers at random for the purposes of calculation.
Volume = Length x Height x Depth
Density = Weight / Volume
So if for example your sheets of glass are 2m x 3m x 1cm, you're looking at 2x3x.01 = 0.06 cubic metres of glass, per sheet.
If each sheet weight 50kg then
50kg = 0.06 m3
50/6x100 = 833kg per cubic metre
