What factors contribute significantly to the overall external measurement of a wrapped 1.55 ounce Hershey's bar?

Answer

The wrapper and the air gap

When comparing the edible chocolate measurement (the cavity) to the dimensions of the fully packaged bar, external elements play a crucial role in the overall footprint. For the 1.55 ounce Hershey's bar, shipping estimates indicate that the addition of the outer wrapper material and the necessary air gap between the chocolate and the wrapper contribute substantially to the reported external length and width measurements, often making the package larger than the consumer might expect based solely on the chocolate size.
