Hi, it's Daniel Pieper here, I am a carpenter and I use a lot of maths in my work. I'm going to build a deck for a new house. It is going to be 3 metres square. The decking boards are 10cm wide and 3 metres long. How many boards will I need to buy? Have fun trying to work out the problem, if you have any questions, just ask. Daniel.
