求八角棱镜表面积和体积的程序

给定八角棱镜的底长、高度和距离，我们必须找到给定参数的八角棱镜的表面积和体积。八棱柱是一个立体的立体物体，共有10个面、24条边和16个顶点。两端的两个面是八边形，其余面是矩形。

其中a是底长， h是高度， d是八棱柱的距离。

Area = 2 * base * distance 
Surface area = (2 * Area) + ( 8 * base * height ) 
Volume = ( Area * height )

例子：

Input: h = 2, a = 4, d = 3 
Output: 
Surface Area : 112 
Volume : 48
Input: h = 1, a = 6, d = 2 
Output: 
Surface Area : 96 
Volume : 24
