Per:

https://www.raspberrypi.org/documentation/faqs/#power

2.5A is the RECCOMENDED POWER SUPPLY. So easy math 3A. Done.

"We recommend a 2.5A (2500mA) power supply, from a reputable retailer, that
will provide you with enough power to run your Raspberry Pi for most
applications, including use of the 4 USB ports. Very high-demand USB devices
may however require the use of a powered hub. The table below outlines the
specific power requirements of each model."

10 x 3 = 30Amps.
