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.
A right-angled triangular prism is called a right prism. The formula for calculating the volume of a prism is V = B x h, where B = area of base, and h = height of the prism. Tâ¦he area for the base is calculated using the formula B = 1/2(length x height) (area of a triangle). Example: The height of a prism is 10 cm.
