I had just gone to bed after a very hard day when the phone rang. It was a strange farmer. I had never met him before although I had heard people talk about him. He sounded quite nervous and he had been talking for a minute or so before I understood anything. Even then all I could understand was that someone called Milly had had an accident. I hadn’t the slightest idea who she was but I obviously had to go. It had been snowing heavily that day and I didn’t know the way. I had been driving for at least an hour when I finally found his place. He was standing there, waiting for me. 一个长方体所有棱的总长度是64分米，长是宽的3倍，高与宽相等，那么这个长方体的表面积和体积各是多少？
