Can I use old usb cords and chargers with iPad 10 generation

Yes with caveats, but charging will be much slower.

Your iPad10 was supplied with a 20W USB-C Power Adapter. USB-C is the new standard for charging portable devices that is being adopted worldwide, this new standard now becoming mandatory in many countries/regions.

The 20W USB-C Power Adapter will optimally charge your iPad at its maximum charging rate.

You can still charge your new iPad using the older USB Type-A charging outlets. To do so, you simply require a certified USB Type-A to USB-C charging/data cable. These are available from good computer stores - and Apple. Here is one example manufactured by mophie and marketed by Apple:

Always use a Certified USB cable. You should aim to avoid simple plug-adapters - as these do not contain the protective active electronic circuitry intended to protect the iPad from misconnection and potential damage. Certified cables do incorporate the necessary electronics.

Most models of iPad require a Power Adapter rated at 12W or greater to reliably charge. 5W Power Adapters intended for older models of iPhone are inadequate to charge an iPad; if the iPad charges at all, charging will be very slow.

Be aware that many computer USB ports and other USB outlets cannot source sufficient power to charge an iPad. Unless explicitly designed for charging connected devices, these USB ports are typically limited to 0.5-1A @5V (i.e., 2.5-5.0W).

You can use any compatible cables, old or new and any compatible charger old or new.

The 10th generation iPad has a USB-C port, so you cannot use old Lightning cables, but you can use a USB-C to USB-A cable and an older USB-A charger just fine.

The older chargers may take longer to charge the iPad however, but there is no risk of damage or harm.

You cannot use old USB-A to Lightning cables like the one below:
