A4纸是我们在办公中经常会用到的纸，大部分的A4纸在打印完以后，就失去了价值，进入了碎纸机。但是只要我们留点心，其实用完的A4纸还能有其它的用途，就是变身为收纳盒，听起来有点不可思议？其实很简单，几步就能做到，接下来，就拿张A4纸，跟着优居网小编动起来吧！

首先我们准备一张A4纸(如果你家里有带图案的A4大小的纸，那更好不过)，然后将纸张进行对折(将长的边对折)，需要对折两次，最后长的边会有四等的分折痕。（如下图所示）

然后还原到对折一次的样子，将下方的两角往中间那条线对折成三角形，上方两角选上面一页纸进行对折。（如下图所示）

接着将折纸模型的左边梯形结构向右边进行翻折。还原后，再将右边梯形结构向左边翻折。（如下图所示）

两边还原后，将上面一页梯形结构的纸往下翻折，刚好和下方形状重叠。（如下图所示）
![](https://wkrtcs.bdimg.com/rtcs/image?w=550.00&md5sum=42a565b5c4f04a20d543d2250bcdf8f2&sign=a2b1d828d7&rtcs_flag=1&rtcs_ver=4&l=webapp&bucketNum=446&ipr={"t":"img","r":"r_2","w":"550.00","h":"193.00","dataType":"jpeg","c":"word/media/image5.jpeg","imgOriW":550,"imgOriH":193})
折叠过后，梯形结构的纸和下面那张纸会形成一个口袋。（如下图所示）
![](https://wkrtcs.bdimg.com/rtcs/image?w=550.00&md5sum=42a565b5c4f04a20d543d2250bcdf8f2&sign=a2b1d828d7&rtcs_flag=1&rtcs_ver=4&l=webapp&bucketNum=446&ipr={"t":"img","r":"r_2","w":"550.00","h":"191.00","dataType":"jpeg","c":"word/media/image6.jpeg","imgOriW":550,"imgOriH":191})
将口袋往上推展开，会形成一个缺一边的长方体。（如下图所示）
![](https://wkrtcs.bdimg.com/rtcs/image?w=550.00&md5sum=42a565b5c4f04a20d543d2250bcdf8f2&sign=a2b1d828d7&rtcs_flag=1&rtcs_ver=4&l=webapp&bucketNum=446&ipr={"t":"img","r":"r_2","w":"550.00","h":"190.00","dataType":"jpeg","c":"word/media/image7.jpeg","imgOriW":550,"imgOriH":190})
然后将图中圈住的那部分正方形按对角线对折，对角线是从右上角到左下角，折叠后会形成两个三角。（如下图所示）
![](https://wkrtcs.bdimg.com/rtcs/image?w=550.00&md5sum=42a565b5c4f04a20d543d2250bcdf8f2&sign=a2b1d828d7&rtcs_flag=1&rtcs_ver=4&l=webapp&bucketNum=446&ipr={"t":"img","r":"r_2","w":"550.00","h":"194.00","dataType":"jpeg","c":"word/media/image8.jpeg","imgOriW":550,"imgOriH":194})
最后将两个三角分别插入左右外部两侧的三角中，盒子就完成了。（如下图所示）

![](https://wkrtcs.bdimg.com/rtcs/image?w=550.00&md5sum=42a565b5c4f04a20d543d2250bcdf8f2&sign=a2b1d828d7&rtcs_flag=1&rtcs_ver=4&l=webapp&bucketNum=446&ipr={"t":"img","r":"r_2","w":"550.00","h":"402.00","dataType":"jpeg","c":"word/media/image10.jpeg","imgOriW":550,"imgOriH":402})
标准的A4纸做出来的盒子长度会有7.5cm,作为笔盒什么的绝对绰绰有余哦，也可以用来收纳袜子、明信片什么的。

如果你家没有标准的A4纸，其它差不多比例的纸也是可以的哦，你的做好了吗？
