Specify volume and select unit of volume measurement. Then, select material for which to perform the calculation, and press Calculate button. The weight of the selected material is calculated based on the material density and its given volume.The number enclosed in square brackets is the item's density in kilogram per cubic meter. The calculator converts the weight, volume and density into many units of measurement.he weight of the selected material is calculated based on the material density and its given volume.

Scientists can tell whether organisms are closely related by  comparing their DNA. This will allow then to look at various traits  and features so as to compare the relationâ¦ship between organisms.
Organisms differ in their form, structure and mode of living. Hence, based on their similarities they should be grouped. The grouping of related organisms helps us in studying their evolutionary relationships. Classification is the division of organisms on the basis of characteristics into groups and sub-groups.A characteristic may be a particular form or function.History of classification. â¢ Aristotle, the Greek philosopher, classified animals based on whether they live on land, in water or in the air.rganisms differ in their form, structure and mode of living. Hence, based on their similarities they should be grouped. The grouping of related organisms helps us in studying their evolutionary relationships.
