Planning & EstimatingQuestion 605 of 700
A wall is 9 ft high and 40 ft long and will be covered with 4x8 sheathing panels. Ignoring openings, what is the MINIMUM number of full sheets (round up)?
a.12 sheets
b.11 sheets
c.45 sheets
d.360 sheets
Explanation
Wall area = 9 x 40 = 360 sq ft. Each 4x8 sheet = 32 sq ft. 360 / 32 = 11.25, round up to 12 sheets (a). Option (b) rounds down, leaving a gap. Option (c) mistakenly divides by 8 (panel length) instead of area. Option (d) confuses square feet with sheets.
