Going to a bigger planet offers more possibilities. Quote Link to comment Share on other sites More sharing options...

0 roolstar Posted February 4, 2008 Report Share Posted February 4, 2008 straight: 314.17 sq ft. Twisted: earths surface area- 314.17 sq ft. Actually the twisted version will be: Earths surface area - 0 sq ft. (Why make a big area with the fence wire if you want to substract it from trhe Earth's area? Just put it somewhere on the floor in a ball) Quote Link to comment Share on other sites More sharing options...
