Problem:
A polyhedron has vertices with the coordinates $\left(
\begin{array}{ccc}
 0.565 & 0.603 & 0.87 \\
 0.124 & 0.476 & 0.183 \\
 0.451 & 0.179 & 0.687 \\
 0.67 & 0.121 & 0.192 \\
\end{array}
\right)$. Estimate the polyhedron's surface area, volume, and the solid angle at the first listed point p spanned by edges with common point p.
Answer:
Solid Angle: $0.28$ 
Surface Area: $0.69$ 
Volume: $0.02$
