A subfloor takeoff uses standard 4 ft by 8 ft wood structural panels. What area is covered by one full panel before cuts?
Correct Answer
D) 32 sf
A full 4 ft by 8 ft panel covers 4 x 8 = 32 sf before cuts. Other choices use nonstandard sheet dimensions or arithmetic errors.
Why This Is the Correct Answer
A full 4 ft by 8 ft panel covers 4 x 8 = 32 sf before cuts. Other choices use nonstandard sheet dimensions or arithmetic errors.
Why the Other Options Are Wrong
Option A: 24 sf
In wood framing, 24 sf is the wrong selection for Panel dimensions: 24 sf is a different published number than the cited Panel dimensions value; Wood structural panel standard sheet size supports 32 sf.
Option B: 28 sf
The trap in B is 28 sf. That selection is wrong because 28 sf is a different published number than the cited Panel dimensions value; Wood structural panel standard sheet size supports 32 sf; A 4 ft by 8 ft panel covers 32 square feet.
Option C: 36 sf
Choice C gives 36 sf. Its specific error: 36 sf is a different published number than the cited Panel dimensions value; Wood structural panel standard sheet size supports 32 sf. The accepted answer is 32 sf.
Memory Technique
Link panel dimensions to its book condition; a different condition means a different answer than 32 sf.
Reference Hint
Open Carpentry and Building Construction, 2016; use Wood structural panel standard sheet size to confirm that A full 4 ft by 8 ft panel covers 4 x 8 = 32 sf before cuts.
