Anyone help me to work out thickness of plastic sheet,i got the lenght:765 meter,width: 775mm ,weight:495 kgs?

density of plastic is 1040kg/m3 thanksAnyone help me to work out thickness of plastic sheet,i got the lenght:765 meter,width: 775mm ,weight:495 kgs?
Weight = volume x density


495kg = 765m*.775m*thickness in meters*1040kg/m^3





solving to t





t = .000803 m or 0.803 mm thick





checking


495 = 765*.775*.803/1000*1040


495 = 495 ok





thkckness is about 0.803 mmAnyone help me to work out thickness of plastic sheet,i got the lenght:765 meter,width: 775mm ,weight:495 kgs?
In order to work out the weight of the above mentioned sheet of plastic, you need to know the specific gravity of the plastic that the sheet is made of.
length x with x thickness =volume or m3





so


765m x .775m x Tm = 495 / m3





592.88T = 495


495/ 592.88 = t


t= .83 meters 830 mm
