程序计算三角棱镜的表面积

在数学中，三棱柱是三维立体形状，其两个相同的末端通过相等的平行线连接，并且具有5个面，9个边和6个顶点。

其中“ b”是底边的长度，“ h”是三角形的高度，“ s1，s2，s3”是三角形各边的相应长度，H是棱镜的高度(即以及矩形的长度)。
给定底部，三角形的高度，棱镜的高度和三角形底部的每一边的长度，任务是计算三角形棱镜的表面积。
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 
 

计算表面积的公式：
如上所述，棱镜包含区域(1/2)*(b)*(h)的两个三角形和区域H * s1，H * s2和H * s3的三个矩形。
现在，在添加所有项之后，我们得到了总表面积：

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