12 Bags of concrete will weight about 276.923 pounds. You need to do 600 divided by 26 for an individual bag. Then multiply the answer you get from it by 12 to find out the amount for 12 bags.
Let's take the first derivative:
Notice that we can write this as:
By taking the derivative of both sides 
times, we get:
This means that each time you take a derivative, a factor of 
will appear. So we conclude that:
Taking 
and 
, we get:
So we finally get:
