in a defined forest area. The timber volume being assessed should be defined, such as gross commercial volume poles, sawlogs, chipwood or some other criteria. Each product has market specifications by which the assessment is made. The timber volume of an individual log standing as a tree can be calculated from measurements of the diameter at breast height over bark (DBHOB) of the tree, the length of the log in the tree, and by applying a taper function for that particular timber species.
The amount of water contained in a pond or water feature, usually measured in litres. Multiply length x width x depth in metres and multiply the result by 1000 to give the volume in litres. For more accurate pond volume calculation information Chart
the size, or amount of material, an FIBC can hold measured as the length times width times height for a sewn bag, but is a more complicated calculation for a tubular bag. The perimeter of the base is considered to be the circumference of a circle, from which the area is then calculated. This area is then multiplied by the height minus 4 inches to calculate the volume. This adjustment is made to account for the fact that a bag will tend to 'swell' outwards and 'shrink' in height somewhat when filled.
