长方体铁皮,长30厘米,宽25厘米,从四个角切掉5厘米的正方体,然后做成盒子,这个盒子的容积有多少毫升.
盒子长：30-2×5＝20（厘米）
盒子宽：25-2×5＝15（厘米）
盒子高：5厘米
容积：20×15×5
＝300×5
＝1500（立方厘米）＝1500（毫升）
30-2*5=20
25-2*5=15
15*20=300毫升
绝对正确
30-2×5=20CM 20×15×5=1500平方厘米
25-2×5=15CM

Bob Dylan 的 《Blowing In The Wind》
How many roads must a man walk down
Before you call him a man?
Yes, 'n' how many seas must a white dove sail
Before she sleeps in the sand?
Yes, 'n' how many times must the cannon balls fly
Before they're forever banned?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
How many times must a man look up
Before he can see the sky?
Yes, 'n' how many ears must one man have
Before he can hear people cry?
Yes, 'n' how many deaths will it take till he knows
That too many people have died?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
How many years can a mountain exist
Before it's washed to the sea?
Yes, 'n' how many years can some people exist
Before they're allowed to be free?
Yes, 'n' how many times can a man turn his head,
Pretending he just doesn't see?
The answer, my friend, is blowin' in the wind,
The answer is blowin' in the wind.
