It has been said in problem description:
For each test case you should output 2 real numbers: the volume and surface area of the hull with precision 0.01

Precision should be 0.01

But in the sample output the precision is 0.0001

BTW, what should I output if all the points share the same line or the same plane?

And another question:

In the output format it's stated 'output the volume and surface area'

But in the sample output the surface area comes before the volume

What shall I do?

I have fixed the error in description. First should be output area, next volume. Precision in output can be any 0.01, 0.0001 or even 0.000001, but judge check only 0.01.
