1 stack= 1 week
100 building blocks
Problem: Build a tower taking as little time as possible to build it.
There are three possible ways that you could build the tower. You could do 2 stacks of 50 which equals 2 weeks to complete, 5 stacks of 20 which takes 5 weeks to complete, or 4 stacks of 25 and takes 4 weeks to complete.
The best way to complete the tower would be to make 2 stacks of 50 so that you are only using 2 weeks.
Answer: It would take 2 weeks to finish the tower.
