What is the mass (in grams and lbs.) of the paint layer? density / volume / mass?

Question

Another question im stumped on:
A certain paint has a density of 0.914 g/mL. You need to cover a wall that is 7.6 meters long and 2.74 meters wide with a layer of paint that is 0.13 mm thick. What volume of paint (in liters and gallons) is required? What is the mass (in grams and pounds) of the paint layer?

thanks!

Answer 1

Figure out the volume (the paint layer is a rectangular solid).

Density = mass/volume. Rearrange the equation to solve for mass (you're given density in the problem).

Good luck.
