Hiya, I need a bit of advice or help. Feel really silly asking this but I am trying to calculate how many decking boards I need. Please can anyone help me? The area is 3. 6m x3m so 10. 8m2. The decking boards are 3600mm in length, 125mm width and 38mm depth. Does anyone know how I would work out how many decking boards I would need please? This has confused me lol
