Yes, somewhere down there.
Seriously, it's impossible to know without measuring that exact material in your particular room. It's well known that thick 703 works well, so I suggest you get started and see where that takes you. Also, it's better to cover more total corner surface with less effective traps, than use fewer traps that each absorb more. See my Density Report for more on this:
