Show the working

1. Sort the three finished outside dimensions: 30 ≥ 20 ≥ 10 in.
2. Treat the longest side as length = 30 in.
3. Girth = 2 × (20 + 10) = 60 in.
4. Length + girth = 30 + 60 = 90 in.

This is a geometry and reference-limit planning check, not a carrier acceptance decision. Measure the finished package at its extreme outside dimensions and verify the current service guide, rounding method, irregular-package rules and surcharge thresholds.
