One gallon of paint (3.79 Liters) covers an area of 26.0 m2. What is the thickness (in mm) of the fresh paint on the wall.
Please help, I have no idea where to start thank you!
If this is in your physics assignment, I would discuss with my parents how to drop the class quickly.
The volume on the wall is 1 gallon, or 231inches cubed, or you need it in cm^2
Volume=1gallon*3.79liters/gal*1000cm^3/liter= you do it.
now, thickness*area=volume
thickness=volume/area=above/26*100^2 cm^2
that will give thickness in cm, convert to mm
