Determine the number of 4-foot-wide by 8-foot-high sheets of drywall needed for the ceiling of the residence in Figure 16.18. The ceiling is flat. Add 5 percent waste.
What will be an ideal response?
The ceiling area and number of sheets of drywall is determined as follows:
Ceiling area (sf) = 36? × 26? – 4? × 12?6? = 886 sf
Area per sheet = 4' × 8' = 32 sf
Sheets of drywall = 886 sf / 32 sf per sheet = 27.7 sheets
Add waste.
Sheets of drywall = 27.7 sheets × 1.05 = 29.1 – Order 29 or 30 sheets
