The volume of any prism is the product of the area of the base and the distance between the two bases. [8] In the case of a triangular prism, its base is a triangle, so its volume can be calculated by multiplying the area of a triangle and the length of the prism: , where b is the length of one side of the triangle, h is the length of an ...
In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench , a trough can be a narrow basin or a geologic rift . These features often form at the rim of tectonic plates .
In the mathematical discipline of graph theory, a graph labeling is the assignment of labels, traditionally represented by integers, to edges and/or vertices of a graph. [1] Formally, given a graph G = (V, E), a vertex labeling is a function of V to a set of labels; a graph with such a function defined is called a vertex-labeled graph.
Graph of a triangular bipyramid According to Steinitz's theorem , a graph can be represented as the skeleton of a polyhedron if it is a planar (the edges of the graph do not cross, but intersect at the point) and three-connected graph (one of any two vertices leaves a connected subgraph when removed).
1. A book, book graph, or triangular book is a complete tripartite graph K 1,1,n; a collection of n triangles joined at a shared edge. 2. Another type of graph, also called a book, or a quadrilateral book, is a collection of 4-cycles joined at a shared edge; the Cartesian product of a star with an edge. 3.
The triangular-prism-first orthographic projection of the tetrahedral prism into 3D space has a projection envelope in the shape of a triangular prism. The two tetrahedral cells are projected onto the triangular ends of the prism, each with a vertex that projects to the center of the respective triangular face.

The graph of a truncated tetrahedron. In the mathematical field of graph theory, a truncated tetrahedral graph is an Archimedean graph, the graph of vertices and edges of the truncated tetrahedron, one of the Archimedean solids. It has 12 vertices and 18 edges. [13] It is a connected cubic graph, [14] and connected cubic transitive graph. [15]
