Cos(arcsin(u)) = √(1 - u²)
_____
You want cos(α) where sin(α) = u.
You know that
cos(α)² + sin(α)² = 1
cos(α)² = 1 - sin(α)² = 1 - u²
cos(α) = √(1 - u²)
Volume of the 1st package : 8.5x11x2 =187 in³
Volume of the 2nd package = 17.5x12x10 = 2,100 in³
Number of packages that fit = V₂/V₁ = 2100/187 = 11.23 Packages
You see I need to know also the reproduction rate as well to equalize it. If 9% of the population declines each year from 2001 to 2021, around 21,006 would die by 2021. Which is 180% more than the population. If the reproduction rate isn't high enough to beat the declination rates, they'd be extinct by then.
2+2=4
