Why This Is the Correct Answer
A 2 ft by 4 ft acoustical ceiling panel covers 8 sf before cuts. Other choices describe 2 ft by 2 ft, 2 ft by 3 ft, or nonstandard panel areas.
Why the Other Options Are Wrong
Option B: 4 sf
In finishes, 4 sf is the wrong selection for Acoustical ceiling tile area: 4 sf is a different published number than the cited Acoustical ceiling tile area value; Acoustical ceiling panel sizing supports 8 sf.
Option C: 6 sf
The trap in C is 6 sf. That selection is wrong because 6 sf is a different published number than the cited Acoustical ceiling tile area value; Acoustical ceiling panel sizing supports 8 sf; A 2 ft by 4 ft ceiling panel covers 8 square feet.
Option D: 10 sf
Choice D gives 10 sf. Its specific error: 10 sf is a different published number than the cited Acoustical ceiling tile area value; Acoustical ceiling panel sizing supports 8 sf. The accepted answer is 8 sf.
