Ah, although your diagram uses symbols for L2 switches, I did wonder if they were L3 switches when you mentioned routing on them.
As @MHM Cisco World notes, you likely need to enable IP routing so you can route. (BTW, "likely" because on small Cisco L3 switches, often IP routing is off by default, but on large Cisco L3 switches, often IP routing is on by default.)
As @MHM Cisco World also notes, your default static route statement, on sw9 is incorrect. It should be:
ip route 0.0.0.0 0.0.0.0 12.0.0.105
I.e. the next hop for all your switches should be the directly connected router interface's IP.
Additionally, if R2 is representative of all your routers, they all will need the correct static route statements.
Basically, you need a static route statement for any network that's not on a directly connected router interface. In some situations, a default route statement can be used (as it can be used on the switches). For example, R1 and R3 only need a default static route statement using R2's interface IP that connects to them. R2, though, needs either a static route statement for each network on the "far side" of R1 and R3, or it could also use a default route statement in lieu of one or more of those individual route statements, e.g. a default route statement directly toward R1 would replace the two route statements needed for the two "far side" networks.
Making these noted changes should get your pings to work, but there are other "improvements" that might be made to your configs. Also, rather than using static route statements, you could use a dynamic routing protocol.
