C 3. Draw the remaining numbers on the following cube, making sure it is accurate with its net. 4. Express the number of faces, edges and vertices of the following prism in terms of the number of sides on its base face. 5. An icosahedron has 20 faces, which are equilateral triangles. 5 such of these faces meet at one vertex. How many vertices are there in an icosahedron? 6. Using Euler’s formula: a) How many edges are there on a prism with 26 vertices, and 15 faces? How many sides are there on the base polygon? b) How many edges are there on a prism with 10 vertices, and 7 faces? How many sides are there on the base polygon? 7.
