Q: Charlie put 25L water to a 長方 box, the water high 12.5 cm,I want to ask the water's 面積是多少平方厘米?
Sol:
25L ＝ 25000ml ＝ 25000 cm^3
Suppose V for volume, h for height and A for area
V ＝ hA ( 體積 ＝ 高度 × 面積 )
25000 ＝ 12.5A
A ＝ 2000
Ans: 2000 cm^2

For 1L=1000cm^3
the water's surface area:
=25000/12.5
=2000cm^2
the water's surface area:
=25000/12.5
=2000cm^2

The answer is:
25L ＝ 25000ml ＝ 25000 cm^3
Suppose V for volume, h for height and A for area
V ＝ hA ( 體積 ＝ 高度 × 面積 )
25000 ＝ 12.5A
A ＝ 2000
Ans: 2000 cm^2
