It would take 65433661 years to re-create the Sahara Desert
<h3>How many years would it take to re-create the Sahara Desert?</h3>
The given parameters are:
Surface area = 9,400,400 km^2
Depth = 150 m
This means that the volume is
Volume = Surface area * Depth
So, we have
Volume = 9,400,400 km^2 * 150 m
Express as meter square
Volume = 9,400,400 * 1000000 m^2 * 150 m
Evaluate the product
Volume = 9,400,400 * 150,000,000 m^3
A small dump holds 20.5 m^3 for 30 seconds.
So, the duration is:
Time = (9,400,400 * 150,000,000 m^3)/(20.5 m^3 per 30 seconds)
Evaluate the product and quotient
Time = 2.0635024e+15 seconds
1 second = 3.171e-8 year.
So, we have:
Time = 2.0635024e+15 * 3.171e-8 year
Evaluate the product
Time = 65433661.104 years
Approximate
Time = 65433661 years
Hence, it would take 65433661 years to re-create the Sahara Desert
