How many sq. m can a 1L paint(100% solids) cover if allowed to spread to even surface to a thickness of 25um?
A liter of paint (100% solids) is applied to a perfectly even surface(assumption only). How much area in sq. m. can it cover if allowed to spread to a uniform thickness of 25 micrometers. (No direct answer please! Must show computation.

Volume = thickness x area
1L = 0.001 m^3 = 0.000025m x area
area = 0.001 m^3 / 0.000025m = 40 m^2
So your answer is 40 square meters.
Good luck.

The question is erroneously written. Paint can't be made of 100% solids and spread. There has to be some vehicle (solvent) for the paint to spread on the surface. If there is a vehicle, then it is not 100% solid. The only way paint could be 100% solid is if it were dry. Dry paint doesn't spread well. It would remain in the shape of the can.
So technically, the answer is 0, since paint can't break the laws of physics.
