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)

Break down the question into 3 parts
1 what is the volume in cm3 of 2.87g of Al using the density you're given?
2 given the other dimensions what is the thickness in cm
3 convert that value from cm to inch
