TECHNICAL TIP OF THE WEEK – Drywall 06302010 Problem: Determine the amount of drywall (sheetrock) needed to sheetrock (drywall) a room measuring 16’ feet x 25’ feet with a 10’ foot ceiling. We will see later that the height of the ceiling is an important factor. Using the following formula, find the number of sheets required. Formula: 16’ + 16’ + 25’ + 25’ = 82’ linear feet 82’ l.f. x 10’ (ceiling height) = 820 square feet 820 s.f. / 40 s.f. (1 sheet of drywall 4’ wide x 10’ tall) = 20.5 sheets Always good to add about 5% for damage and waste (amounts may vary depending on job conditions) To add the ceiling quantity use the following method Formula: 16’ x 25’ = 400 s.f. 400 s.f. / 40s.f. = 10 sheets Solution: The room will require 31 sheets
