Im looking for a calculator or a formula or something that will work
out the cheapest (least amount of lengths) way to cut lengths of 2.4m
wood

The wood comes in lengths of 2.4m and i have to cut various sizes i.e.

6 lengths at 1219mm
6 lengths at 737mm
12 lengths at 303mm
8 lengths at 481mm
+ a few more

The wood is quite expensive so obviously the least amount of scrap the
better.
Is there a web page or a good way to calculate it out?

TIA

Doug
