To solve for the thickness of the latter of oil, we can simply divide the volume by the total surface area:
Thickness = Volume / Surface Area
We are both given the volume and the surface area, all we have to do now is to convert the units in like terms so that we can cancel those out.
Surface Area = 0.50 acres (1.0 x 10^4 m^2 / 2.47 acres)
Surface Area = 2,024.29 m^2
Further converting this into cm:
Surface Area = 2,024.29 m^2 (100 cm / m)^2
Surface Area = 20,242,914.98 cm^2
Therefore the thickness is:
Thickness = 5.0 cm^3 / 20,242,914.98 cm^2
Thickness = 2.47 x 10^-7 cm
or
Thickness = 2.47 x 10^-9 m = 2.47 nm = 24.7 A
