The question is :"the length of each wooden block shown in the figure is L. How the wooden blocks should be arranged so that the total lengths of the two blocks that overhang the bottom block is maximum?" I actually more interest about the method you use to solve this question, i hope you use some mathematical method instead of logic or common sense (cause once you can solve in mathematical style, this is the most logical way already) Now let's think further, what is the arrangement if the number of wooden block become 4, 5, 6,..., n blocks. Please describe how u solve it, if can, explain with a diagram. your reply is meaningful to me, thanks you!!
