YaSvoboden Posted December 20, 2017 Share Posted December 20, 2017 One side of the small is 40%, or 2/5, of the large. It isn't clear that the rectangles are similar, but they should be. Volume = LxWxH Volume of the small = 2/5Lx2/5Wx2/5H = (8/125)LxWxH Quote Link to comment Share on other sites More sharing options...
