So im trying to find the thickness of an aluminum foil sheet

"Aluminum metal has a density of 2.70 g/cm3. Calculate the thickness, in inches, of a piece of Aluminum foil weighing 2.87g and measuring 300mm by 0.500 meters."

so this is what i have so far:

(2.87g)(1mc3)(1m )(1000mm)( 1 )

(2.70g)(1000cm)(1m )( (300)(500)mm2)

if anyone can help, please do, im confused on what to do next, and if what i got is correct so far

(using dimensional analysis)
