They are called SIMILAR.
A polyhedron is a simply connected 3-dimensional shape whose faces are all regular polygons. A hexagonal pyramid is a special case in which one face is a hexagon and six faces are triangles.
You can have two shapes - a small one and a big one - whose angles are congruent but the sides are not. In that case the shapes are not congruent but similar.
It means that the shape of the object doesn't fit into a small list of predefined shapes (for which simple formulae for volume and surface area are known). Such a list may typically include shapes like spheres, rectangular boxes, cylinders, pyramids, cones, certain sections (cutouts) of the previous ones, etc.
They are the objects whose measured speed as a function of time agrees well with theory.
An Allen screw is a screw whose head has a hexagonal socket.

There are 18 edges in a hexagonal prism.There are 6 edges on each of the 2 hexagons.Then there are 6 edges connecting the 6 vertices of one hexagon to the 6 vertices of the other hexagon.A hexagonal prism has 8 faces, 18 edges and 12 vertices.----------------An n-gonal prism has 3n edges. 18A hexagonal prism has eighteen edges.86 faces2 basesAssuming that by "sides" you mean what are technically called "faces", eight: The two hexagonal ends, and the six sides.Google "define:prism": A solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.

Elongated shapes are ones whose measurement in one dimension is larger than in others. It refers to an object which is long.
A decagon.
They are shapes whose exterior sides are all equal in length.
It means that the shape of the object doesn't fit into a small list of predefined shapes (for which simple formulae for volume and surface area are known). Such a list may typically include shapes like spheres, rectangular boxes, cylinders, pyramids, cones, certain sections (cutouts) of the previous ones, etc.
the objects whose density is more than that of fluid sink in the liquid
Mississippi and Alabama
Quail, quarter, quill and quilt are objects. They begin with the letter q.
