Hi,

re: Reply

there are 35  highlight_green%2840in%29 lengths:  

Each of the 40in lengths will allow for 6 whole pieces of 6 1/4 in long  to cut from it.  (the rest is waste)

6 1/4 in is 25/4 in

%2840%2F%2825%2F4%29%29=+40%284%2F25%29 = 160/25 = 6.4,  6 can be cut from each 40in length.

So the total number of pieces from all of the 40in lengths is:

 6•35 = 210 pieces in all
