One gallon of paint covers an area of 25.0m虏. What is the thickness of the paint on the wall?

Its for my physics class. Im just a bit confused on how im supposed to find this without the mass.One gallon of paint covers an area of 25.0m虏. What is the thickness of the paint on the wall?
thats a tough question.





lets recognize that we are trying to find the volume of a rectangle essentially.





it is 5m L x 5m W x t H, where t=thickness of paint





so we have 25t = volume





your volume can be converted by changing 1 gallon to liters





the conversion is 1 gallon = 3.78541 liters





we also know that 1L = .001m^3, so 3.79L = .00378541 m^3





so we now have





25t = 3.79 x 10^-3


t = 1.514 x 10^-4 meters


t = .1514mm





Hope this helps!
