Which is bigger 0.5 meters or 50.5 centimeters?
As 0.5 metres = 50 centimetres then 50.5 centimetres is bigger.
How many meters squared in an area with a known oil of 200 cubed centimeters and a thickness of 0.5nm?
I am sure you meant 0.5mm thickness. Otherwise 0.5 nanometre is a VERY thin film. If thickness is 0.5mm then it will be equal to 0.05cm thickness Area = volume / thickness = 200 / .05 = 4000 square cm 4000 square cm / (100*100) = 0.4 square metres If you meant 0.5 nanometers then the area = 4 million square metres
