whats a cubic

whats a cubic What’s a cubic refers to the cubic measurement used in shipping to determine dimensional weight. Carriers like USPS, UPS, and FedEx calculate shipping charges not just by actual weight but also by the package’s volume in cubic feet or inches. This is especially important for lightweight but bulky items. The formula for cubic feet is length × width × height ÷ 1728. Understanding dimensional pricing helps e-commerce sellers optimize packaging and reduce shipping costs by avoiding overpaying for empty space.
