  • Decompose the cross-section and calculate component and total areas.
  • 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.
