WebPerimeter of a Hexagon: The perimeter of a hexagon is the sum of the length of all 6 sides. Perimeter = AB + BC + CD + DE +EF + FA. In regular hexagons, all sides are equal in length. So, the perimeter of a regular hexagon is six times the length of one side. Perimeter = a + a + a + a + a + a = 6 a.

WebThe answer is NO. You cannot make a regular polyhedron out of regular hexagons. This is becaue the interior angles of at least 3 hexagons that meet at a single vertex add up to 360 degrees. Therefore, that arrangement of hexagons can only exist in 2-D space; there is no “extra” space left for the shape to bend into 3 dimensions. howick act 1831WebThe so-called Platonic solids have fascinated mathematicians and artists for over 2000 years.
