- Calculate boundary lengths, including a missing sloping length using Pythagoras where required.
- Calculate prism volume from cross-sectional area and constant depth.
- Apply unit prices, fixed fees, percentage allowances and whole-unit purchasing rules.
- Combine component costs into a complete project quote.
- Evaluate assumptions and limitations and justify a decision using calculated evidence.
