计算四面体的面积和体积的程序

四面体只是具有三角形底面的金字塔。它是一个具有四个三角形面，三个侧面或侧面，一个在底部或底部以及四个顶点或拐角的固体对象。如果面都是全等边三角形，则将四面体称为正则面。

四面体的面积可以使用以下公式找到：

Area = sqrt(3)*(side*side)

例子 ：

Input : side = 3
Output : 15.5885

Input : side = 20
Output : 692.82

输出 ：

Area of Tetrahedron =15.5885

四面体的体积可通过以下公式求出：

Volume = a³/(6√2)

Input : side = 3
Output : 3.18


Input : side = 20
Output : 942.81
