Length of the sheet is given as
[tex]L = \frac{200}{3} yards = 6096 cm[/tex]
width of the sheet is given as
[tex]w = 12 inches = 30.48 cm[/tex]
now let say its thickness is "t"
so the volume of the sheet is given as
[tex]V = L*w*t[/tex]
[tex]V = 6096*30.48* t[/tex]
[tex]V = 185806.08*t cm^3[/tex]
mass of the sheet is given as
[tex]m = 0.83 kg = 830 gram[/tex]
now we have
[tex]density = \frac{mass}{volume}[/tex]
[tex]2.70 = \frac{830}{185806.08*t}[/tex]
by solving above we have
[tex]t = 1.65 * 10^{-3} cm[/tex]
so the thickness of sheet will be above
