Nets worksheet: Answers and working
Part A: Working out and filling in
1. 36 cm
How many edges does a cube have? Each one is 3 cm.
A cube has 12 equal edges: 12 × 3 = 36.
2. 96 cm
How many edges does a cube have? Each one is 8 cm.
A cube has 12 equal edges: 12 × 8 = 96.
3. 100 cm
A cuboid's edges come in three groups: lengths, widths and heights. How many are in each group? Start with 11 + 5 + 9.
There are 4 edges of each length: 4 × (11 + 5 + 9) = 4 × 25 = 100.
Part B: Choose, or true or false
4. A
Check each shape: is there a 2 × 2 block? Are there more than 4 squares in a line?
A cube net: 6 squares, no 2 × 2 block, at most 4 in a line, no two faces folding onto each other.
5. False
How many sides does each 7-sided end have? Each side joins one rectangular face: count those faces, then compare with 6.
Both ends have 7 sides, and each side of an end joins one rectangular side face: 7 rectangles.
6. C
A square pyramid has a square base and how many triangles? See whether a triangle joins every side of the square.
A square pyramid has a square base and 4 triangular sides: a triangle on each side of the square.
7. False
Count the squares, look for a 2 × 2 block or more than 4 in a line, then fold it in your head.
Fold it in your head: the 6 squares must each take a different face, none overlapping.
8. C
What faces does a triangular prism have? Count each shape's rectangles and triangles, then see where the triangles sit.
A triangular prism has 3 rectangular sides and 2 triangular ends: the rectangles in a row, one triangle above and one below.
9. C. 6 cm × 3 cm
The base is length × width. Which face is opposite the base, and how do opposite faces of a cuboid compare?
A cuboid's opposite faces match: the top is also 6 cm × 3 cm.
10. D
A cylinder has two circular ends and a curved side that opens out into a rectangle. Check where each shape puts its two circles.
A cylinder's net is a rectangle with a circle on each long side.
11. B. 3 cm × 7 cm
The base is length × width. Which face is opposite the base, and how do opposite faces of a cuboid compare?
A cuboid's opposite faces match: the top is also 3 cm × 7 cm.
12. False
How many sides does each 8-sided end have? Each side joins one rectangular face: count those faces, then compare with 7.
Both ends have 8 sides, and each side of an end joins one rectangular side face: 8 rectangles.
Part C: Word problems
Marking: 2 for the working, 1 for the answer, 1 for the sentence.
13. A
Check each shape: a 2 × 2 block, more than 4 in a line, or two squares landing on the same face all rule it out.
Only one shape folds with its 6 squares closing up a cube.
14. 196 cm
The wire needed is all the edges added up. How many edges are there of each length?
The frame is the 12 edges, 4 of each length: 4 × (23 + 9 + 17) = 196.
15. D
A triangular prism has three rectangles and two triangles. See whether each shape's two triangles would fold onto the same end.
A triangular prism: 3 rectangles in a row, one triangle above and one below.
16. 2 cm
All of a cube's edges are equal. Count how many it has, then share the 24 cm equally among them.
A cube has 12 equal edges: 24 ÷ 12 = 2.
17. B
A triangular prism has three rectangles and two triangles. See whether each shape's two triangles would fold onto the same end.
A triangular prism: 3 rectangles in a row, one triangle above and one below.
18. 6 cm
All of a cube's edges are equal. Count how many it has, then share the 72 cm equally among them.
A cube has 12 equal edges: 72 ÷ 12 = 6.
