Estimate of tree weight: [(dbh x 1.5)/2]2 x [tree height] x [density of living tissue reckoned to be 0.9 Mg/m3].
Estimate of soil weight: [soil volume] x [(dry bulk density of soil reckoned to be 1.72 Mg/m3) รท (0.35 Mg/m3 of soil moisture held in 35% porosity)].
Estimated weight of steel structure given by project engineer.
Container diameter varies from 7.0 to 9.0 m, with the midpoint used in calculation of soil volume.
