The value 75.4 = 24 π, where 24 π substitutes for factor of 12 π in the formula for a volume of frustum of a cone encompassing a full tree using one base circumference, converting it to a volume formula that uses a basal circumference that is the average of circumferences C 1 and C 2.
A volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume. Difficulties ...
Foresters also perform tree volume measurements. A detailed guideline to these basic measurements is provided in The Tree Measuring Guidelines of the Eastern Native Tree Society [1] by Will Blozan. [2] [3] These are summaries of how to measure trees are also presented by various groups involved in documenting big trees around the world.
Volume table – a chart based on volume equations that uses correlations between certain aspects of a tree to estimate the standing volume; Stand density management diagram – model that uses current stand density to project future stand composition; Volume can be calculated from the metrics recorded in a plot sample.
Allometry studies the relative size of organs or parts of organisms. Tree allometry narrows the definition to applications involving measurements of the growth or size of trees. Allometric relationships often are used to estimate difficult tree measurements, such as volume, from an easily measured attribute such as diameter at breast height (DBH).

The crown shape will be used to derive a crown form (CF) value for different tree shapes and will be the third parameter of the crown volume calculation formula. The crown of a tree can be subdivided into 10 disks each representing 1/10 of the height of the crown.
