01 / QUICK RECAP
Connect the ideas.
- Surface area counts the exposed faces; volume measures the space inside.
- For a right prism, volume equals cross-sectional area multiplied by length.
- A cylinder has two circular ends and a curved rectangle when it is closed.
- Square and cubic unit conversions use squared and cubed scale factors.
- Compare measurement error with the accepted reference value; round the final result to a sensible precision.
