T16.1 · RuleAlways convert mm to metres first, show every line of working, write the unit, and round up whole sheets and lengths.T16.2 · VolumeVolume (m³) = L × W × T in metres. Example (2016): 10 boards × 5.3 × 0.25 × 0.1 = 1.325 m³; × $100 = $132.50.T16.3 · LinearLinear metre cost = total length (m) × $/m. Example (2022 stool): top 2 × 0.3 m × $13.00 = $7.80; legs 4 × 0.2 × $7.25 = $5.80; rails 4 × 0.2 × $1.95 = $1.56; total $15.16.T16.4 · SheetsSheets: pieces per sheet from the layout; total pieces ÷ pieces per sheet, then round up. Example (2019): 150 boxes × 5 pieces = 750; 12 per sheet gives 62.5, so 63 sheets.T16.5 · FinishFinish: area × coats ÷ coverage = litres; × price. Example (2023): 2.5 × 1.5 = 3.75 m² × 2 coats = 7.5 m² ÷ 15 m²/L = 0.5 L × $45 = $22.50.T16.6 · Cutting listCutting list: count each part from the drawing, and remember overhangs. In 2021 the top overhung the frame by 40 mm all round, which adds 80 mm to each dimension. Read the whole description before calculating (NESA 2021 feedback).
