Cheh, Vincent Orange, and Muriel Bowser to dedicate the 1800 block of Martin L. King, Jr. Avenue as Butch Hopkins Way. ANACOSTIA ECONOMIC DEVELOPMENT CORPORATION.
The dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex. The pentagonal faces of this solid are a bit more difficult to deal with than the others. The calculations below are for a dodecahedron of side length s.
The icosehedron and the dodecahedron are 'duals' (as are the cube and the octahedron). By 'dual' is meant that if you put a vertex in the middle of all of the faces and connect the lines, you get the dual. By placing a vertex at the middle of all the faces of the dodecahedron you get an icosahedron, and vice-versa. Figure 4 shows the dual nature of the icosahedron and dodecahedron.
