Normally, the Basic Education comprises the study of the equations of first and second degree. Most of the textbooks do not address higher order equations. For this reason, we developed a didactic proposal addressing the third degree equation in Hight School. Thus, our main objective is to verify the feasibility of studying cubic equations in this stage of education. However, we began our study having as a motivator trouble finding the approximate number of molecules of air (real gas) contained in a car tire on road conditions, which allowed us to find the number of moles in the Van der Waals Equations and with that, we fall back on solving an equation of the third degree starting it is study.
