（3）按每千克涂料粉刷3.5 m2计算，可求出共需要涂料：1600÷3.5≈460（千克）；（4）根据涂料的型号及费用，选择合适的涂料。师：选择涂料时，要考虑很多因素，如价格、耐用期、消费心理、环保等，要怎么选择呢？学生可以把几种涂料进行对比，一起讨论决定，同时学会在交流中理解接纳别人较好的建议：如：A型，优点：价格便宜，需要19桶，总共才5700元；缺点：耐用期太短，两年后又要重新粉刷；B-1型和B-2型，虽然桶装量不同，但价格和耐用期都处在中游水平；C型和D型，优点：耐用期长，最划算；缺点：价格太高，不符合人们的消费心理，也不可能持续那么长时间，至少5年就要更换一下样子。综合以上价格、耐用期、消费心理，选择B-1或B-2型比较划算。而这两种比较来看，B-2型更便宜一些，所以，最后确立用B-2型涂料。
