What is priority mail cubic

Priority Mail Cubic is a shipping service offered by the United States Postal Service (USPS) that allows customers to ship packages of various shapes and sizes, including irregularly shaped items, at a flat rate based on the package's volume.

Here are some key features of Priority Mail Cubic:

  2. Cubic pricing: The price is calculated based on the package's length, width, and height (in inches). The USPS uses a formula to calculate the volume of the package, and then applies a flat rate based on that volume.
