Glazing Maths: Pane Size from Supplied Pocket Dimensions

Glazing Maths: Pane Size from Supplied Pocket Dimensions

Original quantitative topic practice in English. All 24 questions are included in a shuffled order. Each question supplies its own data and model assumptions; use only those assumptions. Choose one answer. Practice target: 20/24, not an official examination pass mark. Keep full intermediate precision. These exercises cover the calculation scope in the title; they do not constitute a full Red Seal examination, trade qualification, site design or operating specification.

For this drawing exercise a rectangular pocket measures 1300×1700 mm. The supplied detail requires 4 mm clearance on EVERY side. Pane thickness is 6 mm and glass density is supplied as 2500 kg/m³. A perimeter strip follows the pane edge and needs 30 mm total extra at its join. These dimensions do not establish a safe glazing specification. Calculate the pane area in square metres. Keep intermediate values unrounded; round the final answer to 4 decimal places if needed.
