Anyone know formular to work out weight and length of plastic sheet if thickness: 1.30mm and width: 404mm?

specific gravity is 1.04 (or 1040 kg/c3 thanksAnyone know formular to work out weight and length of plastic sheet if thickness: 1.30mm and width: 404mm?
*I'm going to use a density of 1040 kg/m^3. You've written 1040 kg/cm^3. Specific gravity is relative to water, which has a density of 1000kg/m^3


------





Find the volume of the sheet: L*w*h = L*0.404*0.0013 = 0.0005252*L m^3


then use the density: (0.0005252*L)*1040 kg/m^3 = 0.5462*L kg





Your final formula is: W = 0.5462*L kg, where W is the weight of the sheet in kg, and L is the length of the sheet in m.





To find out how much a desired length of sheet weighs, substitute a number (in meters) for L. To find what length corresponds to a desired weight, rearrange for L and substitute a number (in kilograms) for W.
