Fermi problems are problems that, being difficult to solve, can be satisfactorily solved if they are broken down into smaller pieces that are solved separately. In this article, we present inconceivable magnitude estimation problems as a subset of Fermi problems. Based on data collected from a study carried out with 12 to 16 years old students, we describe the different strategies for solving the problems that were proposed by the students, and discuss the potential of these strategies to successfully solve the problems.
