About two centuries ago, Benjamin Franklin showed that 1 tsp of oil would cover about 0.5 acre of still water. If 1.0 x 10^4 m^2 = 2.47 acres, and there are about 5 cm3 in a tablespoon, what is the thickness of the layer of oil?

The oil cover will have the shape of a prism: one cross section in contact with the water, and the other cross section with air. Have everything first in the same units (preferably cm). Find the area the oil covers in cm^2, and use the given volume to get the thickness. __________________ Jerry (Working, studying, writing and drawing :3) It is easier to protect your feet with slippers than to cover the earth with carpet.
