Level 1 · Warm-up
1 How many faces does a cube have?
Show worked solution
A cube has 6 faces.
2 I have one curved surface and no flat faces at all. What am I?
Show worked solution
That is a sphere.
3 How many edges does a cube have?
Show worked solution
4 + 4 + 4 = 12 edges.
Level 2 · Core
4 A square pyramid has a square base and triangular sides. How many faces does it have altogether?
Show worked solution
1 square base + 4 triangles = 5 faces.
5 I have one circular face and one point. What am I?
Show worked solution
That is a cone.
6 A triangular prism has 2 triangular faces and 3 rectangular ones. How many faces altogether?
Show worked solution
2 + 3 = 5 faces.
Level 3 · Challenge
7 How many MORE edges does a cube have than a square pyramid?
Show worked solution
A cube has 12 edges and a square pyramid has 8, so 12 − 8 = 4 more.
8 A triangular prism has 5 faces and 6 vertices. How many edges does it have?
Show worked solution
3 + 3 around the two ends, plus 3 joining them: 9 edges.
9 Which has more vertices: a cube or a square pyramid, and by how many?
Show worked solution
A cube has 8 vertices and a square pyramid has 5 (4 base corners + 1 apex), so cube by 3.

10 How many MORE edges does a cube have than a square pyramid?
Show worked solution
A cube has 12 edges. A square pyramid has 4 base edges + 4 sloping edges = 8 edges. The difference is 12 − 8 = 4.
