Consider the following problem: A box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutting out a square from each of the four corners and bending up the sides. Find the largest volume that such a box can have. Let x denote the length of the side of the square being cut out. Let y denote the length of the base.
(a) Draw several diagrams to illustrate the situation, some short boxes with large bases and some tall boxes with small bases. Find the volumes of several such boxes. (Do this on paper. Your teacher may ask you to turn in this work.)
(b) Draw a diagram illustrating the general situation. Introduce notation and label the diagram with your symbols. (Do this on paper. Your teacher may ask you to turn in this work.)
(c) Write an expression for the volume V.
V = _____?
(d) Use the given information to write an equation that relates the variables. (Do this on paper. Your teacher may ask you to turn in this

意思如下:
考虑下面的问题：一个开放的机顶盒是从一个纸板方片，3英尺宽，削减了从四角每平方和弯曲了双方建造。求量最大，这样可以有一个盒子。让X表示对被切断了广场边长。 y表示该基地的长度。
（1）画出几个图来说明情况，大基地和基地的一些小高一些短期盒盒。找到几个这样的箱子的数量。 （请在纸上的。你的老师可能会要求您把这项工作。）
（二）画出一个图，说明一般的情况。符号和标签介绍与您的符号图。 （请在纸上的。你的老师可能会要求您把这项工作。）
（三）写的数量表达五
V = _____?
（四）使用给定的资料，写一个方程式，涉及的变量。 （请在纸上的。你的老师可能会要求您把这项工作。）
（五）使用部分（四）写作为x的函数的数量
五（十）= ___？
（六）完成通过寻找解决的最大音量，这样的盒子可以有问题。
V = _____ft ^ 3
