I have 2 questions

Ok first question why are the smaller aircraft “777-200LR” “A330-200” which pretty short in size why do they have a longer range span than aircraft such as the A340-600 and 777-300ER im so confused like doesnt a bigger plane have more/larger fuel tanks…for example the 767-300ER and 767-400ER are almost the same but 763 can fly much further,like whats the point making a larger plane that cant fly as far???

also why do some planes have weird numbers like

737-8FE or A330-313X

Like i know the engines are different but like is that all it is?

More weight, more airframe, more payload capacity, more thrust from engine = worse fuel economy.

Question 1:
The 777-200LR and A330-200, are still big planes, but are built to have more fuel tanks, and lesser passengers than the 777-300ER and A330-300

Question 2.
Boeing uses a customer code, which will be the 2 last digits in the plane type, for example 737-8FE - Which is the 737s of Virgin Australia.
Airbus uses the last 2 digits, as a way to show the given engine type. A330-313X is the A330-300 with Rolls Royce Trent 700, instead of CFM-6 or PW4000.

Hope this answers your question. :)
