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 48 m2. What are the dimensions of the prism? square sides = sqr4 = 2m area of one side of prism = 48 / 4 = 12 m2 height of prism = 12 / 2 = 6m dimensions = 2m, 2m, 6m Also I would appreciate if someone could review how to find the area of a rectangular prism from 3 dimensions.
