Actually this is a classic optics problem. If you were to consult any
advanced optics text you would see this. For reference consider a planar
Fabry Perot etalon with perfectly reflecting mirrors.

Anyway; if you allow that all of the energy is relected you will have an
INFINITE number of reflections. Provided you do not include a mechanism
for removing energy from the shock waves.

See Ma I learned something in college.

for once I can comment about something I know about.

---------------------------------------------------
Well, you get a limit situation of a VERY large amount of reflections
with VERY little energy each!
For simplicity's sake I'll keep using 4 sides for reflection, thank you.
I don't feel like using integrals and an hour's worth of maths to calculate an
effect such as this.
If you want a mathematical nightmare, let's say the grenade blows up in an
apartment, close to a closed window [which will break and not totally reflect
the blast] , and with assorted pieces of furniture that affect the blast
reflection, but which are not bolted to the floor, and as such will move with
the blast, affecting the power of the reflection...... bweeehhh..

Point being: Let's keep this simple please.
