计算三角棱镜表面积的程序

在数学中，三棱柱是由相等的平行线连接两个相同端部的三维立体形状，有5个面、9条边和6个顶点。

其中“b”是底边的长度，“h”是三角形的高度，“s1, s2, s3”是三角形各边的长度，H是棱柱的高度（即也是矩形的长度）。
给定底、三角形的高、棱柱的高和三角形底边各边的长度，任务是计算三棱柱的表面积。
例子：

Input: b = 3, h = 4, s1 = 3, s2 = 6, s3 = 6, Ht = 8 
Output: The area of triangular prism is 132.000000
Input: b = 2, h = 3, s1 = 4, s2 = 5, s3 = 6, Ht = 8 
Output: The area of triangular prism is 126.000000 
 

表面积计算公式：
如上所述，棱镜包含面积为(1/2)*(b)*(h) 的两个三角形和面积为H*s1、H*s2 和 H*s3 的三个矩形。
现在在添加所有项后，我们得到总表面积：

SA = b * h + (s1 + s2 + s3 ) * H
