Final answer:
The surcharge pricing for a 6 lb package measuring 95'' cannot be determined without additional carrier-specific information on size and weight surcharge criteria. The provided pricing model covers weight but not dimensions or oversized package fees.
Step-by-step explanation:
If a standard post package weighs 6 lbs and measures 95'', the surcharge pricing will depend on specific carrier size and weight limits which aren't given in the question.
The weight in ounces is 6 lbs x 16 oz/lb = 96 oz. The pricing model provided in the references applies to the first 3 ounces and each additional ounce, but it does not mention surcharges based on dimensions or total weight that would exceed standard limits.
Therefore, with the given information, it is not possible to determine the surcharge pricing without the carrier's additional detail on surcharge criteria related to size or over-limit weight.
Moreover, the package's length alone (95'') could cause it to fall into an oversized category, which usually incurs additional fees entirely separate from the weight-based pricing.
Companies like USPS, UPS, and FedEx typically have surcharges for oversized or unusually shaped packages, but that information needs to be referenced from their specific pricing schedules.
