eight times as many as a car .as many as 怎么用法

as many as 意思是：和……一样多.似乎很少见到.
A is three(four,etc.) times as big(high,long,wide,etc) as B
表示A是B的3（4）倍大/高/长/宽……
除此之外,表示倍数还有两种说法：1.A is three(four,etc.) times the size(height,length,width,etc) of B A是B的3（4）倍大/高/长/宽……
2.A is three(four,etc.) times bigger (higher,longer,wider,etc) than B A比B大/高/长/宽3（4）倍.
