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.
find the lateral area and the surface area of the solid the first thing we should know is that since it s a rectangular prism there could be 3 different pairs of bases here to start we ll stay that the 7 cm 2 cm side is our base the perimeter of our base is 7 2 7 2 or 18 cm the height is 13 cm our rectangular bases are equal to their length times their width or 7 cm 2 cm 14 cm2 that means the surface area is 262 cm2 and the lateral area when the base is 7 cm 2 cm is 234 cm2
