✔ 最佳答案

長方體長100cm，闊50cm，等於5000立方cm。注水至20cm高，相當於注入 20ｘ50 = 1000mL。因為注入1000mL除以1000mL(因為1000mL=1L，所以這樣除)，結果是注入1L。

The five "fuwas" that have the meaning of "Welcome to Beijing" are the offical mascots of Beijing 2008 Olympic Games.

Volume = 100 cm x 50 cm x 20 cm = 100000 cm^3.
1L = 10 cm x 10 cm x 10 cm = 1000 cm^2.
So volume = 100000/1000 = 100L.
