Problem Description
The surface area and volume of the three-dimensional figure are calculated.

From the diagram, we can extract the common attribute to the parent class rect: Length: L Width: h height: Z

In the parent class Rect, define Method area () for method length () and bottom area for the perimeter of the bottom surface.

Defines the subclass cube class cubic of the parent class rect, calculates the surface area and volume of the cube. The method in which the surface area () overrides the parent class.

Defines the subclass four pyramid class Pyramid of the parent class rect, calculates the surface area and volume of the pyramid. The method in which the surface area () overrides the parent class.

Enter the length (l), Width (h), and High (z) data of the cubic graph, respectively outputting the surface area and volume of the cuboid, the surface area and the volume of the pyramid.

Input
Enter multiple rows of numeric data (double);

Three values per line, representing L H Z, respectively

If there is a non positive number in the input data, it does not represent any graphics, surface area and volume are 0.

Output
The number of rows corresponds to the input, the numerical value is rectangular surface area cuboid Volume four Pyramid area Pyramid volume (there is a space in the middle as the interval, the value of two decimal places)

Sample Input
1 2 3
0 2 3
-1 2 3
3 4 5
Sample Output
22.00 6.00 11.25 2.00
0.00 0.00 0.00 0.00
0.00 0.00 0.00 0.00
94.00 60.00 49.04 20.00
Hint
Four pyramid formula: v=1/3sh,s--Bottom Area h--high
