355 [ SQRT{72}xS^2xT - 9xSxT^2 + ( SQRT{2} + 4 )xT^3 ]x[( SQRT{8} + 1 )xS - ( SQRT{8} - 2 )xT ]
AREA = ------ x ----------------------------------------------------------------------------------------------------------------
2712 [(( SQRT{8} + 1 )xSxT/2 ) - (( T^2 )/( 12 - SQRT{128}))]


S = width or height of the Cubic Yoid

T = edge or cross section depth

#note that T =< Sx[( SQRT{5} - 1 )/2 ]
