Answer
$19.32 g/ 1 cm^3=19.32 g/cm^3$
$27.63 g/19.32 g/cm^3=1.430 cm^3$
$1.430 cm^3/100^3=1.430*10^{-6} m^3$
$1.430*10^{-6} m^3\div(1*10^{-6})m=1.430 m^2$
Work Step by Step
The density of gold = mass of gold/volume of gold
Convert the unit into meter$^3$ by using (1m=100cm)$^3$
z=1*10$^{-6}$ m according to the metric prefixes.
$volume=base area*thickness$
$area=volume/thickness$
