Yes.
Were working out coverage from a 20kg bag.
Goalposts have moved anyway, Its a formula I should have to hand really.20kg gives 4m2 at 3mm thick
20kg gives 0.8m2 at 15mm thickI now need to find the coverage for 10mm thick. So we can work out how many 20kg bags we need.
I think 11.7mm would be 1m but then the next sum doesnt work so I dont think im working it out right, or even close.
Im multiplying the mm by 3 and dividing the m2 by 3.Flippin contractors!
I'm going with 1.1m2 per 20kg at 10mm deep.
Ive drawn a graph and everything.
.mo.
If I have 4m2 at 3mm thick would I get 12m2 at 1mm thick?
Im sure I would. But doubt can be a powerful thing.
