The accuracy of volumetric computation of small diameter logs based on mathematical formulae was evaluated. Plantation logs of 13-year-old Hopea odorata with diameter measurements of 20 to 30 cm were assessed using Huber’s, Smalian’s, Newton’s and truncated cone formulae. The reference volume of eac...
