consider a major oil spill in a lake ( a prototype situation related to Alaska Oil Spill few years ago and many subsequent spills) Amount of oil spilled is 2.9 mega gram (Mg). We can assume oil and water dont mix, so all oil floats on water beacuse density of the spilled oil is 0.796g/mL. The length and width of the lake affected are 265.0 miles and 9.18 x 10^5 yards,respectively. Estimate thickness of the oil film ( in cm)?
