Windows 10 In need of help with a Network question - this is for online course I am taking

Help me with a Router Network question....I am confused - For online course

Open
So I am taking an Intro to Network class thru an online college.
I have a course project that I modify each week....its a wiring diagram.
As per the course instruction, the diagram looks like this:

Internet--->Modem--->24port switch--->3 individual router--->three offices (each router running cat6 to their assigned desktop)

Instructors comments were: You must subnet your network. This means that you must take your Class C and break that into 4 networks which is a /26 for each wireless router then a spare /26 - - - -
you could have subnetted your network:

192.168.0.0 /26
192.168.0.64 /26
192.168.0.128 /26
192.168.0.192 /26

So my question is what is the IP address for each router? And also each router will have 2Wifi devices so whats the range on those devices look like?
Please assist me. I'm at a loss. I reached out to him but he is not getting back to me.

It's arbitrary. Just pick an address for each router in their subnet range

But typically the router will be assigned the first device address in the subnet so a typical setup would be:​

192.168.0.0 /26 will have

subnetwork address 192.168.0.0 /26​

router address 192.168.0.1​

available device addresses range 192.168.0.2 - 192.168.0.62​

subnet broadcast address 192.168.0.63​

192.168.0.64 /26

subnetwork address 192.168.0.64 /26​

router address 192.168.0.65​

available device addresses range 192.168.0.66 - 192.168.0.126​

subnet broadcast address 192.168.0.127​

192.168.0.128 /26

subnetwork address 192.168.0.128 /26​

router address 192.168.0.129/26​

available device addresses range 192.168.0.130 - 192.168.0.190​

subnet broadcast address 192.168.0.191​

192.168.0.192 /26

subnetwork address 192.168.0.192 /26​

router address 192.168.0.193/26​

available device addresses range 192.168.0.194 - 192.168.0.254​

subnet broadcast address 192.168.0.255​
