How many vertices has a cuboid? How many edges has a cuboid? How many faces has a cube?

Here are the solutions to the mathematics questions:

1. A cuboid has 8 vertices (corners). The correct option is (b).

   $$\boxed{\text{b) 8}}$$

2. A cuboid has 12 edges. The correct option is (a).

   $$\boxed{\text{a) 12}}$$

3. A cube has 6 faces. The correct option is (c).

   $$\boxed{\text{c) 6}}$$

4. A cylinder has no vertices. The correct option is (d).

   $$\boxed{\text{d) no vertice}}$$

5. A cylinder has 1 curved face (the lateral surface). The correct option is (a).

   $$\boxed{\text{a) 1}}$$

6. An example of a common object with the shape of a cuboid is a block. A book is also a cuboid. The correct option is (a).

   $$\boxed{\text{a) block}}$$
