Answer:
A=331.84 m2
Step-by-step explanation:
Hello
The density of a object is defined by
[tex]d=\frac{m}{v}[/tex]
d is the density
m is the mass of the object
v es the volume of the object
We have
[tex]thickness= t =2.87 * 10^{-7} m\\\ A=unknown=area\\ Volume=Area*thickness\\m=1 kg \\\\\\d=10500kg/m^{3}[/tex]
[tex]d=\frac{m}{v}\\ v=\frac{m}{d}\\ A*t=\frac{m}{d}\\ A=\frac{m}{d*t}\\ \\A=\frac{1 kg}{10500\frac{kg}{m^{3} }*2.87*10^{-7}m}\\A=331.84m^{2}[/tex]
I hope it helps
