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.
These are the only vertices in the prism. So V = 6. There are 3 edges to form each of the triangles, and there are 3 edges to connect the 2 bases (turning the sides into rectangles). So the number of edges is 9. The name of the prism tells us how many lateral sides there are -- triangular -3 lateral sides or faces .
