Gold has a density of 19.3 g/cm3. The thickness of a piece of gold leaf weighing 1.93 mg and covering an area of 14.5 cm2 is?

I solved for volume=10000cm3
then I solved for height and got 690cm is the thickness of gold leaf. Can anyone confirm or deny?

  1. volume of 10,000 cc is correct.
    10,000 = 14.5 x 14.5 x thickness
    Solve for thickness. 690 cm sounds way too large to me.
