The aim of this study was to assess the combined effects of the synthetic cannabinoid agonist nabilone and Î´ 9 -tetrahydrocannabinol (Î´ 9 -THC) using drug-discrimination procedures, which are sensitive to drug interactions.
Pentagonal Prism. In a prism there are two equal and similar end faces, parallel to each other, joined together by other rectangular faces. In some cases, the faces joining the end faces may be parallelograms instead of rectangles. There are many types of Prism, and they are named after the shape of their base. A prism having pentagonal base faces is called a pentagonal prism. It is a type of heptahedron with 7 faces, 15 edges, and 10 vertices.
There are eight vertices in a rectangular prism. Any prism is a three dimensional figure; it has two bases and is formed by rectangles connecting the edges of each base to each other. So in the case of a rectangular prism is a rectangle. Thus, the number of faces of any prism is the number of edges of the base + 2. Also, the number of vertices is just the number of vertices of the base shape, times two. A rectangular prism has eight vertices because the base (a rectangle) has four vertices. That times two is eight.
