Hi.
I am not sure how to proceed with this problem...
Is it necessary to convert from cubic cm (in the grams per cm^3) to square feet (the plane of the mirror) by dividing by height??? I would guess the height of the cubed measurement of silver to be 2.18975 and so I wold divide to get cm^2, then later convert to ft^2. Am I way off in this line of thinking?
Any help appreciated. Thank you...

If one gram of silver can be converted into 400 square feet of mirrors, how thick is the coating? The density of silver is 10.5 grams per cm^3.
