From Wikipedia, the free encyclopedia. Mutual fund fees and expenses are charges that may be incurred by investors who hold mutual funds. Running a mutual fund involves costs, including shareholder transaction costs, investment advisory fees, and marketing and distribution expenses.
prism - a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms. polyhedron - a solid figure bounded by plane polygons or faces. parallelepiped, parallelepipedon, parallelopiped, parallelopipedon - a prism whose bases are parallelograms.
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.
