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 the prism is equal to the perimeter of the base times the sum of the apothem of the polygon and the height of the prism. Surface area of a regular hexagonal prism = 6as + 6sh. = 6s(a + h). Where, a = apothem height, b = side of the base and h = height of the prism.
