Answer:
191433.4 hours 
Explanation:
We are given that In the average US household, the television is on 6.75 hours/day! How many hours will have passed after 77.7 years (the average lifeexpectancy of an American)?
1 year - 365 days
Given that the television is on 6.75 hours/day.
If 1 year = 365 days 
Convert 77.7 years to days by multiplying it by 365
77.7 × 365 = 28360.5 days
So the number of hours will be:
28360.5 × 6.75 = 191433.375 hours 
Therefore, 191433.4 hours will pass.

We know density = Mass / Volume
So Volume = Mass/Density
 Volume =  Area * Thickness 

So the approximate thickness of the foil in millimeters =
