Painting Records: Net Area and Measured Coverage

Painting Records: Net Area and Measured Coverage

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.

Paint 4 identical rectangular walls, each 5 m wide and 2.5 m high. Across the entire job there are 2 unpainted openings, each 1 by 2 m. The measured total consumption is 12 L for 2 complete coats. A label comparison value is 10 m²/L per coat. Ignore spills and differences among coats. Calculate the measured coverage in m²/L per coat. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
