Primary 5 Maths: 3-D Shapes and Nets — Practice Paper 1 (10 Questions)
Primary 5 Maths: 3-D Shapes and Nets — Practice Paper 1 (10 Questions)
Paper 1 practises three things only: faces, edges and vertices of prisms and pyramids, a cylinder counted with its curved side kept apart, and the check faces + vertices − edges = 2. Take a real box out and count while touching it.
Quick answer 10 questions, about 20 minutes. Items 05 to 07 are full counts of a prism and a pyramid, items 08 and 09 work backwards from the number of faces, and item 10 is the commonest error.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 6 faces | A top, a bottom and four side faces make 6; counting them one by one with a hand is safest. |
| 2 | 12 edges | Four on the top, four on the bottom and four upright: 4 + 4 + 4 = 12. Counting one face only gives 8. |
| 3 | 10 vertices | Vertices are twice the number of base sides (one ring top, one bottom): 5 × 2 = 10. |
| 4 | 3 faces: 2 flat and 1 curved | The two circles are flat and the rolled side is curved, so 3 faces, not 6. |
| 5 | 5 faces, 9 edges, 6 vertices | Two triangular ends plus three rectangular sides make 5 faces; edges give 3 × 3 = 9 and vertices 3 × 2 = 6. |
| 6 | 5 faces, 8 edges, 5 vertices | One square base plus four triangular sides make 5 faces; four sloping edges plus four base edges give 8, and the vertices are 4 plus the apex. |
| 7 | 18 edges | A prism has three edges per base side: 6 × 3 = 18. Checking with faces + vertices − edges = 2 gives 8 + 12 − 18 = 2. |
| 8 | base 6-sided (a six-sided prism), 18 edges | A prism has two bases, so there are 8 − 2 = 6 side faces and the base is a hexagon; the edges are 6 × 3 = 18. |
| 9 | base 5-sided (a five-sided pyramid), 6 vertices | A pyramid has a single base, so 6 − 1 = 5 side faces, a five-sided pyramid; vertices are 5 round the base plus the apex, 6 in all. |
| 10 | 3 faces (2 flat + 1 curved) | A cylinder is not a box: two circular ends and one curved surface. Feel each face before counting and keep flat and curved apart. |
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.
