This research aims to investigate the use of digital technologies by a group of high school students on the theme of some elements and properties of the metric space geometry, specifically the volume of cubes and pyramids, and the relationship betwen them. The question constituted around these assumptions, is to investigate how a didactic approach that addresses the use of the software GeoGebra 5, which has 3D capabilities, contributes to subsidize the understanding of high school students on topics related to the properties of geometric solids In particular, cube and pyramid. The subjects, five students from a private school in São Paulo, used GeoGebra software, version 5, in two sessions, aiming to announce conjectures about the properties linked to volume cubes and pyramids and the relation between these objects. After collecting and analyzing data, it was realize the end of the investigation that elements such as visualization, experimentation and the dynamism of the interface have competed from the engendered strategy for the subsidy to understanding certain relationships, properties and results would be hampered otherwise
