Answer:
t= 0.0003 mm
Explanation:
Given that
mass ,m = 230 mg
m = 0.23 g
Area ,A= 23 x 17 cm²
A= 391 cm²
Density ,ρ = 19.32 g/cm³
Lets take thinness of the sheet = t cm
We know that
Mass = Density x Volume
m = ρ A t
Now by putting the values in the above equation we get
0.23 = 19.32 x 391 x t
[tex]t=\dfrac{0.23}{19.32\times 391}\ cm[/tex]
t=0.000030 cm
t= 0.0003 mm
That is why the thickness of the sheet will be 0.0003 mm.
