Point 2: 1/3 from the foundation on theheight of the pyramid
Explanation:
The inner squares of the board are situated on the upper wall of the half-cube, and the rest on the side walls. The down wall is without squares !
I1( Integral debute ) = А
I2 ( Integral mittelspiel ) = B – А
I3 ( Integral endspiel ) = C – B
А
B
C
