Gold can be hammered into extremely thin sheets called gold leaf. If a 212-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft ✕ 1.0 ft,what is the average thickness of the sheet in meters? Explain how you got the answer step by step if you can.

Thank you for the opportunity to help you with your question!

212mg=0.212gm

1foot=0.3048m

2.4foot=0.73152

denisty=19.32g/cm^3

19.32/1000000

1.932 x 10^-5g/m^3

d=m/v

v=m/d

0.212/1.932 X 10^-5

=10973.08m^3

thickness=10973.08/(0.3048 x 0.73152)

=49213.88m

Please let me know if you need any clarification. I'm always happy to answer your questions.
