The cost of exporting cargo using the air transportation method depends on the weight of the export cargo and also the distance between the country of origin and the country of destination. In the air transportation method, to calculate the weight of the export cargo, first the actual weight of the cargo is obtained by weighing, then the volume weight of the cargo is obtained by multiplying the three dimensions of the length, width and outer height of the product (in centimeters meters) in each other and dividing it by the number 6000 is obtained. If the goods are of the same type and in more than one quantity, the number of goods is also multiplied by the dimensions, and if the goods are different, the volumetric weight is calculated for each of the goods and then they are added together. So comparing it with actual and volumetric weight, each of which is heavier, is used in cost calculation.
