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.
No, a prism does not have an apex. A prism is a solid geometric figure with two parallel and congruent bases that are connected by lateral faces. The apex refers to the highest point or vertex of a shape, which is not applicable to prisms.
They are prisms.
Prisms have two parallel and congruent bases connected by rectangular lateral faces, while cylinders have two circular bases connected by a curved lateral surface. Prisms have flat sides and edges, while cylinders have a curved surface.
It is called a prism.
hexagonal prism
No, a prism cannot have curved sides. A prism is a polyhedron with two parallel and congruent polygonal bases connected by lateral faces that are parallelograms. The lateral faces of a prism are always flat, planar surfaces that are perpendicular to the bases. Curved sides would not meet the definition of a prism.
the sphere doesn't have a base because it's all round
Yes, a prism has an even number of vertices. A prism is a three-dimensional shape with two parallel and congruent polygonal bases connected by rectangular or parallelogram faces. The number of vertices in a prism is equal to the number of vertices in its bases plus the number of vertices in the lateral faces. Since each base has an equal number of vertices, and the lateral faces have an even number of vertices, the total number of vertices in a prism is always even.
