Consider a main oil spill in a lake. Amount of oil spilled is 5800.0 kg. We can presume oil and water don't mix. Density of spilled oil is 0.805 g/ml.The length of the lake affected is 350.0 miles as well as width is275.0 miles.
As an environment personnel, your job to approximate thickness of the oil film (in cm).
