I’m an office worker. I like ordering meals on the phone and I often order food from a restaurant in the center of the city. Yesterday I had a bad experience.       1        When I called the restaurant for the first time, nobody answered the phone.      2         I called at least ten times before a girl answered it. I was a little angry. I told the girl my order and then waited for my food.     3    So I called the restaurant again. The girl told me she was too busy. I was so hungry that I decided to get my food myself.        4       木材加工厂要把一块长是10米，宽是2米，高是30厘米的长方体木料横锯成3块板子，那么这3块板子的表面积一共是多少？这3块板子的体积一共是多少？
