Design a wooden deck for an imaginary back yard. Draw it to scale. Calculate the boards needed and the cost.
Steps
1) Sketch the deck shape (rectangle is easy; L-shape is harder). 2) Decide board size (e.g. 2.4 m × 0.14 m). 3) Calculate the deck area. 4) Divide by board area to get number of boards. 5) Multiply by price per board.
Always order 10–15% extra for cuts and waste. Real construction maths includes safety margin.
