Alright, let's explain how to say one thing is bigger than another by a certain amount!
Pronunciation: /ɛks taɪmz ˈbɪɡə/
Meaning: When we say one object is "x times bigger" than another object, we mean it is that many times larger in size. For example, if a car is 2 times bigger than a bike, it means the car is twice as large as the bike.
Sentence: Look at the giant block and the small block. The giant block is 3 times bigger than the small block, so it's much, much larger!
