Those specs are well known and trivial to calculate on your own:
https://www.bitshopper.de/en/shop/sha-256-miner/usb-miner-bitcoin/newpac/45 GH (overclocked) will draw ~10 Watt
10.000 Th = 10.000.000 Gh
10.000.000/45 = 222.223 newpac miners (yes, that number is two hundred twenty two thousand two hunderd twenty three)
222223 miners * 10 Watt/miner = 2222230 Watt = 2222 KiloWatt = 2,2 MegaWatt
Electricity price is usually given in cents/Kwh.
Run those 222223 miners for one hour will use 2222 Kwh.
Prices in my country are about 30 cents/kwh, so in my case, it would cost around 666 euro's PER HOUR... Not including any "extra's", you cannot run these miners in a vacuum... You'll need several hundred's of rPi's, computers or servers and big usb hubs... they all draw power to...
BEFORE you'd actually attempt something like this (very unlikely tough... it would be a hell of a task to set this up, even if you'd manage to get over 200.000 usb miners), you'd only make 0.0036
BTC per hour, with a market value of around 115 euro's, so each hour running this setup you'd lose hundreds of euro's (on your power bill)
