## anonymous 5 years ago The formula I have is to find weight. If I have ther weight(lbs) how do I write this to find Thickness if I have Width, length, and weight Width x Length x Mil ÷ 15 = Lbs./

I think you're being asked to use 'density'. The density of an object is its mass per unit volume;$\rho = \frac{m}{V}$The volume here is (according to you), $V=(length)\times(width)\times(thickness)$and you have the mass (you call it weight, but it's mass). You say you want the 'thickness', so that would be"$\rho = \frac{m}{lwt }\rightarrow t=\frac{m}{\rho lw}$where l is length w is width t is thickness m is mass p is density.
