answer: Sven is helping #Person1# to measure the length of the old workbench. They decide to replace it for a bigger one, which is 3.5m long by 1m wide.
documents: #Person1#: Hi, Sven, can you help me? Could you hold the end of the tape measure, please?
  #Person2#: Of course, where do you want me to stand?
  #Person1#: Just there by the door. I need to measure the length of this workbench. We're going to replace it. OK - 3 m 47 cm. Let's round it up to 3 m 50.
  #Person2#: I'm glad you're replacing it. We need more space to work on things. How deep will the new workbench be?
  #Person1#: Tell me what size you want and I'll order the wood.
  #Person2#: Well, it's about 65 cm at the moment. Could we increase it by about a third?
  #Person1#: Sure. So let's see. We need a piece of wood 3. 5 m long by 1 m wide. I'll order it right away and I'll be able to install it next Tuesday.
