6-8
6-6
6-0
5-9 NOW ADD
-----------------------
23-23 OR WE HAVE 23 FEET 23 INCHES OR 24 FEET 11 INCHES.
TO AVERAGE 6-5 FOR ALL 5 PLAYERS WE NEED A TOTAL OF
5(6-5)=30-25 OR 30 FEET 25 INCHES OR 32 FEET 1 INCH
NOW SUBTRACTING WHAT WE HAVE (24-11) FROM WHAT WE NEED (32-1) WE GET
32-1 WHICH HAS TO BE CONVERTED TO
31-13 SO WE CAN SUBTRACT.
-(24-11)
-----------------
7-2 IS WHAT WE NEED FOR THE CENTER.
PROOF:
6-8
6-6
6-0
5-9
7-2 NOW ADD THE TEAM HEIGHTS
--------------
30-25 OR 32+1 WHICH IS EXACTLY WHAT WE NEED
32*12+1=5*77 (CONVERTING FIGURES TO INCHES)
384+1=385
