03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | Perimeter = 20 cm. | Perimeter is the distance all the way round. |
| 2 | Area = 36 cm squared. | Side times side, with the unit in cm squared. |
| 3 | Volume = 72 cm cubed. | Multiply the three dimensions together. |
| 4 | Area = 63 cm squared. | Base times height, then divide by two. |
| 5 | Area = 65 cm squared. | Use the perpendicular height, not the slant edge. |
| 6 | 3 m 20 cm = 320 cm. | Change the metres part first, then add the centimetres. |
| 7 | Area = 96 cm squared. | Add the parallel sides, times the height, then halve. |
| 8 | 2 500 mL = 2.5 L. | There are 1000 millilitres in a litre. |
| 9 | Surface area = 150 cm squared. | A cube has six equal square faces. |
| 10 | Area = 40 cm squared. | 26 is the perimeter; the area is length times width. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Before calculating, decide whether the question gives a length, an area or a volume, because each converts differently. A perimeter is a line in cm, an area is a surface in cm squared, and a volume fills space in cm cubed. Every area formula needs a base and the matching perpendicular height, and a trapezium needs the two parallel sides added before halving. For reverse questions, work backwards from the formula.Tutor Registration →
