Roof Sheet Layout: Full Width, Cover Width and End Laps

Original quantitative learning practice in English. All 24 questions are included. Four supplied cases exercise six related calculation targets; they form one topic, not four separate tests. Every question includes the complete initial data. Use the stated model and retain intermediate precision. Choose one answer. Learning target: 20/24, not an official pass mark. This bank covers the calculation topic in its title; it is not a complete professional examination, design approval or operating instruction.

A supplied rectangular sheet layout spans 4.2 m across and 6 m down slope. Sheets are 1.2 m wide with side lap 0.2 m between neighbours. Along slope sheets are 3 m long with end lap 0.2 m. First sheets contribute full dimensions; later sheets contribute dimension minus lap. Trim excess at the far boundaries. Ignore ridges, fixings and waste reuse. Calculate the excess coverage width at the far boundary in m. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
