At that time it was called 'The Land of Yan and Zhao', because its northern area was dominated by the Kingdom of Yan, while its southern area was occupied by the Kingdom of Zhao. Today, that same area is home to more than 50 minority ethnic groups, such as Han, Hui, Manchu, Mongolian and Korean.
Pentagonal Prism Formula 1  : Area of Base(A) = Â½ * a * 5 * s Perimeter of Base(P) = 5s Surface Area of Prism = 5as + 5sh = 5as + Ph Volume of Prism = (5/2)ash = Ah. 2  a = apothem length, s = side, h = height.
The surface area of a right prism is 2 Â· B + P Â· h, where B is the area of the base, h the height, and P the base perimeter. The surface area of a right prism whose base is a regular n-sided polygon with side length s and height h is therefore:
