In this type of problems what we have to do is unit conversion. In order to do so we need all the equivalences which we will be mentioning during the explanation of the problem:
First of all the answer is asked to be in acre-feet and we can see the data we are getting from the rain is in not even a volume unit.
To calculate the volume of poured rain we need to have both numbers in the same units, we will convert to
using the equivalence
like this:
it is possible now to calculate the volume () like this:
Now we just need to convert this volume to acre-feet and we will do so using the equivalence like this:
5199.50403658 acre-feet would be the answer to our problem
