Answer:
The thickness of the foil is 0.017 mm.
Explanation:
Given that,
Weight = 7.5 oz = 212.6175 gm
Density = 2.70 g/cm³
Area of aluminium = 50 ft² = 46451.52 cm²
We need to calculate the thickness of the foil
Using formula of density



Where, A = area
t = thickness
m = mass
Put the value into the formula



Hence, The thickness of the foil is 0.017 mm.
