Physics Question:
An aluminum sheet is compressed to a thickness of 2.0 microns. If each cubic
centimeter of aluminum has a mass of 2.70 g, what is the mass of an
aluminum sheet, in grams, if its total surface area is 5 m2? Note: a
micrometer is sometimes called a micron.

Find the volume. You have surface area and thickness, so multiply them. Make sure to be consistent with units, I'd get everything in terms of cm first. 

Then use density = mass/volume, since they gave you the density  (2.70 g/cm^3)
