Example 3
o
Each object above has the shape of a geometric solid. Name the geometric solid
and state the number of flat faces, vertices and the number of edges.
Solution
O The solid is a cube with 6 flat Q The solid is a cone with 1 flat
faces, 8 vertices and 12 edges. face, 1 vertex and 0 edges.
Q The solid is a sphere with 0 flat Q The solid is a cylinderwith 2 flat
faces, 0 vertices and 0 edges. faces, 0 vertices and 0 edges.
