There are 4 (assuming a regular hexagonal prism), (a professional way is that seeing that it has 4 is dividing 8 by 2, for pairs).
There is 1 on the base and 3 more on its sides. 3 + 1 = 4.

How many pairs of parallel faces does a triangular based pyramid have?
A triangular based pyramid has zero pairs of parallel faces. In a triangular based pyramid, all three faces of the base are not parallel to the apex, which means there are no pairs of parallel faces in this type of shape.
How many parallel faces does a pentagonal based prism have?
It can have one, two or three pairs of parallel faces.
What has three pairs of opposite parallel congruent rectangular face?
A cuboid. Or a hexagonal prism. In fact any prism whose base has an even number of sides will have three pairs of opposite parallel congruent faces. All but the cuboid will also have other faces but the question does not exclude them.
Are any of a square based pyramids faces have parallel lines?
Yes. A square consists of two pairs of parallel lines!
How many faces have pairs of parallel edges in a decagonal based prism?
If the prism is based on regular decagons and it is a right prism, all 12 faces.
How many pairs of parallel faces does a hexagonal prism have?
Four.
How many pairs of parallel faces does a triangular based pyramid have?
A triangular based pyramid has zero pairs of parallel faces. In a triangular based pyramid, all three faces of the base are not parallel to the apex, which means there are no pairs of parallel faces in this type of shape.
How many parallel faces are on a hexagonal prism?
For a uniform hexagonal prism, there are four pairs of parallel sides. On a hexagonal prism, the six side faces have interior angles of 120 degrees, so each face is parallel with one three over from it. The ends (base and top) are parallel and 90 degrees from each side.
How many parallel faces does a pentagonal based prism have?
It can have one, two or three pairs of parallel faces.
How many faces have pairs of parallel edges in hexagonal pyramid?
Only the base can have parallel edges since all other faces are triangular. So, at most one face.
How many faces of octahedron are parallel?
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. Some of these have no parallel edges whereas a right hexagonal prism has 4 pairs of parallel faces.
What solid figure has three pairs of parallel parallel faces and all faces are congruent?
A cube has three pairs of parallel faces and all faces are congruent.
What has three pairs of opposite parallel congruent rectangular face?
A cuboid. Or a hexagonal prism. In fact any prism whose base has an even number of sides will have three pairs of opposite parallel congruent faces. All but the cuboid will also have other faces but the question does not exclude them.
How many parallel pairs does a triangular based pyramid have?
A triangular-based pyramid, also called a tetrahedron, has no parallel faces, but has 4 faces, 6 edges and 4 vertices
