cylinder
A prism..
There are 10 parallel lateral edges. And ten parallel edges between the two bases. There could be more - within each decagon, but that depends on the decagons, and details of these are not given.
This is because the amount of refraction taking place at the parallel faces of a glass slab is equal but opposite and since the faces are parallel the emergent ray emerges parallel to the incident ray with lateral displacement.
What makes this question tricky to answer is the understanding of the terms. Were the correct terms used in the question, and does the question poster and answer contributor have the same understanding of those terms? Having said that, here goes. A prism is a polyhedron with at least two congruent parallel faces. They are called the bases. The other faces (the "lateral faces") are parallelograms that are formed by lines that connect the corresponding vertices of the two bases. A quadrangular prism has a quadrangular base (such as a rectangle). If the base is some sort of regular polygon, it's called a regular prism. The lateral area of a prism is defined as the total area of the lateral faces. To calculate the lateral area, you multiply the length of an edge by the perimeter of the face that is perpendicular (at right angles to) to that edge. So, assuming the height, 4 cm in this case, is perpendicular to the perimeter, 16 cm, we calculate the lateral area to be 4 x 16 or 64 square centimeters or 64 cm2.
The nonparallel sides of a trapezoid are called the legs. The parallel sides are called the bases.
Cylinder
A rectangular prism has congruent bases and parallelograms as lateral surfaces.
characteristics are: The lateral faces are triangles. it is three-dimensional. The lateral faces are not congruent.
A prism.
They are prisms.
It is called a prism.
hexagonal prism
The bases of a prism or cylinder are congruent and parallel and they meet the lateral face (cynder) or faces (prism) at right angles. A cross section parallel to the longitudinal axis will, therefore, be a rectangle.
Not true. They have only one base and several (3 or more) lateral triangular faces. A pyramid has a single vertex over a base - there are no parallel faces in any pyramid.
perpendickular
Depends on the type of prism.In Euclidean geometry, a prism is a three dimensional figure, or solid, having five or more faces, each of which is a polygon. Polygons, in turn, consist of any number of straight line segments, arranged to form a flat, closed, two-dimensional figure. Thus, triangles, rectangles, pentagons, hexagons, and so on are all polygons. In addition, a prism has at least two congruent (same size and shape) faces that are parallel to one another. These parallel faces are called bases of the prism, and are often associated with its top and bottom. The remaining faces of a prism, called lateral faces, meet in line segments called lateral edges. Every prism has as many lateral faces, and lateral edges, as its base has sides. Thus, a prism with an octagonal (eight sided) base has eight lateral faces, and eight lateral edges.
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
