Subnetting between routers and multiple VLANs

I have a subnetting problem.
There is routerA connected to another routerB.
RouterB then connects to SwitchA.
SwitchA has 4 VLANs attached to it.
VLAN 10 needs 1500 hosts
VLAN 20 needs 500 hosts
VLAN 30 needs 60 hosts
VLAN 40 needs 30 hosts

The starting network is 10.0.0.0/8
What would the serial interface address, subnet address, and subnet mask be?
