What feature defines dimensional weight pricing?

  1. It is based purely on weight

  2. It is determined by both weight and dimensional measurements

  3. It is applicable only to flat-rate shipping

  4. It is available only for international shipping

The correct answer is: It is determined by both weight and dimensional measurements

Dimensional weight pricing is primarily defined by its consideration of both the actual weight of the package and its dimensional measurements, such as length, width, and height. This pricing structure is implemented because larger packages may occupy more space during shipping, even if they are relatively light. By taking into account both weight and size, shipping companies can more accurately assess the cost associated with transporting a package. This method helps to ensure that the pricing reflects the space a package will take up in a shipping vehicle, which is essential for logistics and efficiency. In contrast, the other options do not accurately capture this dual consideration; they either oversimplify the concept or limit its applicability in ways that are not accurate.
