A) A partly full paint can has 0.747 U.S. gallons of paint left in it. What is the volume of the paint in cubic meters?
I got the answer as 0.00283 cm^3
B) If all the remaining paint is used to coat a wall evenly (wall area = 11.7 m2), how thick is the layer of wet paint?
Im not sure how to solve part B) !

MathMate,
Part A is correct, but the unit should be m³ (cubic metre).
For part B, consider the 0.00283 m³ of paint is used to make a huge but flat box with the same volume, then
11.7 m²*thickness = 0.00283 m³.
Solve for thickness.

drwls,
0.747 gallons * (1 ft^3)/(7.48 gallons) *(0.3048 m/ft)^3 = ___ m^3
b) the volume in m^3 equals the area coverage {in m^2} times the paint coating thickness, in meters.
