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.
A prism is a polyhedron for which the top and bottom faces (known as the bases) are congruent polygons, and all other faces (known as the lateral faces) are rectangles. (Technically, when the sides are rectangles, the shape is known as a right prism, indicating that the lateral faces meet the sides of the base at right angles. In this lesson, when we use the term prism, we mean a right prism. But there are other types of prisms, too.) A prism is described by the shape of its base. For instance, a rectangular prism has bases that are rectangles, and a pentagonal prism has bases that are pentagons.
