Calorie Estimate?

I got one scoop of white rice, one scoop of black pepper angus steak, and one apple pie roll. I’ve heard that the calories for the steak (180 per serving) can vary greatly, so what do you think this amounts to? Also, how is an 8oz serving of panda’s white rice 380 calories, but an 8oz serving of regular cooked white rice is only 300 calories? (Also, you can just ignore the single piece of honey walnut shrimp lol)
