The answer will depend on whether you mean parallel edges or parallel faces.
3 pairs
A cuboid, also known as a rectangular prism, has 4 pairs of parallel sides. This means that it has a total of 12 parallel sides. Each pair of parallel sides is opposite to each other, creating a rectangular shape with equal and parallel sides.
Cuboid or cube
It depends on which type of cuboid we are talking about. If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry. If it is a cuboid with length, width and height all different, then it has three planes of symmetry. If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.
A cuboid has 12 straight edges.
4 parallel edges

Yes, a cuboid does have parallel edges. In a cuboid, all pairs of opposite edges are parallel to each other. Additionally, the opposite faces of a cuboid are also parallel to each other.
3 pairs
3 pairs
Three.
12

A cuboid has 6 faces, and each face has a pair of parallel faces. So, a cuboid has 3 pairs of parallel faces. Mathematically speaking, that's the tea, honey.
A cuboid has 3 pairs of parallel faces.
I'm pretty sure it is 12 pairs of parallel lines.
