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 Prism Formula is given as, Where, a-apothem length of the prism. b-base length of the prism. l-base width of the rectangular prism. h-height of the prism. A prism is a polyhedron with 2 polygonal bases parallel to each other. The two polygonal bases are joined by lateral faces.The number of lateral faces are equal to the number of sides in the base. The lateral faces in a prism are perpendicular to the polygonal bases. Surface area of a prism is the sum of the area of the 2 polygonal bases and the area of the lateral faces.The surface area of a prism is measured in terms of square units.he two polygonal bases are joined by lateral faces. The number of lateral faces are equal to the number of sides in the base. The lateral faces in a prism are perpendicular to the polygonal bases. Surface area of a prism is the sum of the area of the 2 polygonal bases and the area of the lateral faces.
