问题填空题

已知长方体货仓长50米，宽30米，高5米，这个长方体货仓最多可以容纳8立方米的正方体货箱______个．

答案

因为8=2×2×2，所以正方体木箱的棱长是2米，

50÷2=25（个）（横着放的个数），

30÷2=15（个）（竖着放的个数），

5÷2=2（层）…1（米）（能放2层，还余1米空间），

所以能容纳的木箱的个数为：

25×15×2=750（个）．

答：这个长方体货仓最多可以容纳8立方米的正方体货箱750个．

故答案为：750．

Yesterday a school boy is daydreaming in class.Not knowing that he was doing,he put a pen

cap into his mouth.A few minutes late,he was terrified to find that he had swallowed it!The teacher

was shocking when the boy stood up and said,"I've just swallowed a pen cap."He was quickly

sent the nearest hospital.There a doctor examined his and said the best treatment was to take

some medicines so that the pen cap could pass natural.Three hours later the boy successfully

made it."She is really lucky," said the doctor."It's not rare that small children put things into their

mouths for a fun.It's very danger."
