How many cups is 100g of cooked rice?

I'm asking cuz I bought this huge bag of basmati rice today and it's got a carb count of 78.1g per 100g cooked... 8.8 protein... the carb count seems way to high...

(I haven't cooked the rice yet to messure it, since I haven't opened the bag in case I want to return it.)

Any info would be appriciated..
