He can make an infinite number of different polygons,
as long as each one has more than 3 sides.
If the polygon has four sides, then it's always a parallelogram
and a rectangle, and it might also be a square.
(72)p = 76
p = 76/72 = 19/18
Sum of the terms of the series is
Sn = n/2 ( a1+an )
we have n= 6 , a1= 17, an = 57
so Sn = 6/2 ( 17+57) = 3(74) = 222
The answer should be
12ft^3
12cm^3
12yd^3
12in^3
