The aim of this study was to evaluate the precision of the Original Geometric Method and Modified Geometric Method, to estimate the individual volume of 100 trees of Eucalyptus urophylla S. T. Blake, coming from a plantation with high variability of shape, with five years of age, located in Vitória da Conquista, Bahia, Brazil. For this, the trees were rigorously cubed and separated into five diameter classes with an amplitude of 3 cm, and their actual volumes were compared with volumes estimated by the respective methods, in an analysis of variance in factorial with two factors (diameter classes and methods). The results showed that, in general, the methods produced good estimates of volume, however, there was loss of precision in estimates related to a greater taper of the trees belonging to the largest diameter classes (DBH > 12 cm), with shape factors smaller than 0.46, as well as the presence of deformations on the stem.
