19 with 1 remaining
39 - 1 = 38 = 2 x 19
(3 x 39) + 2 = 119 feet.
39*36/2 = 702 diagonals.
39+38+...+1 = 39*38/2 = 494
FIRST...each whole has four-fourths, so there are 156fourths in 39 wholes ( 4 x 39 = 156).NEXT...there are 2 fourths in one-halfTHEREFORE: there are 158 fourths in 39 1/2 (156 + 2)
39 pints x 2 cups/pint = 78 cups
19 and 1/2
39 times
78 ÷ 2 = 39
39*38*37/(3*2*1) = 9139
