01 / QUICK RECAP
Connect the ideas.
- Count only exposed surfaces; add or subtract actual solid volume.
- Similar lengths, areas and volumes use k, k², k³.
- Use measurement bounds and retain exact values until the final calculation.
- Check internal dimensions, whole-unit purchasing and model assumptions.
