- C1000√3/√(2π) m^3
- D1000√3/√π m^3
Explanation
A conical tent with 60-degree vertex angle; the measurements could not be recovered (options involve sqrt forms over pi). The stored key A agrees with the published coaching key (PW, CDS 2 2025 Set A). Note: key disputed - independent verification inconclusive.
