6. What is the length of wall studs when the finished floor-to-ceiling height is 8′, ceiling material is ¾″ thick, the finished floor is ¾″ thick, and it's framed with three plates?
A. 7′9″
***B. 8′1½″
C. 8′
D. 7′7½″
I think the answer is B.
7. A carpenter needs to calculate the correct length of the wall studs for a platform-frame construction. The building will have a finished floor-to-ceiling height of 8′, a ¾″-thick hardwood finish floor, ¾″ furring strips in the ceiling, and ½″ gypsum board on the ceiling. The combined thickness of the top plates and the sole plates is 4½″. What would be the correct stud length for this building?
A. 8′1″
B. 7′10½″
***C. 7′8½″
D. 7′9½″
Is the answer C?
6. You do not say how thick the three plates are
7.
8' + 3/4" + 3/4" + 1/2" = 8' 2" then subtract plates
8' 2" - 4.5" = 7' 14" - 4.5" = 7' 9 1/2"
For 6, they don't tell you the thickness of the three plates.
To find the correct stud length for both questions, we need to calculate the total distance from the floor to the ceiling, accounting for the thickness of the ceiling material, finished floor, and the plates used in framing.
For the first question, the finished floor-to-ceiling height is 8', the ceiling material is ¾" thick, the finished floor is ¾" thick, and it's framed with three plates.
To find the total distance from the floor to the ceiling, we add the heights of each component:
8' (floor-to-ceiling height) + ¾" (ceiling material) + ¾" (finished floor) + 4½" (three plates) = 8' + 2¼" + 2¼" + 4½" = 8' + 9" = 8'9"
Therefore, the correct stud length for the first question is 8'9". However, none of the options provided match this answer. Therefore, none of the given options are correct.
Moving on to the second question, we have a similar situation, but with different measurements.
The finished floor-to-ceiling height is 8', the ¾" hardwood finish floor, ¾" furring strips in the ceiling, and ½" gypsum board on the ceiling. The combined thickness of the top plates and the sole plates is 4½".
To find the total distance from the floor to the ceiling, we add the heights of each component:
8' (floor-to-ceiling height) + ¾" (hardwood finish floor) + ¾" (ceiling furring strips) + ½" (gypsum board) + 4½" (three plates) = 8' + 1¼" + 1¼" + ½" + 4½" = 8' + 7½" = 8'7½"
Therefore, the correct stud length for the second question is 8'7½". The closest option provided is option C, which is 7'8½". However, this does not match the calculated correct answer.
Therefore, the correct stud length for the second question is not provided in the options given.
To summarize:
- The correct stud length for the first question is 8'9" which is not provided in the options.
- The correct stud length for the second question is 8'7½" which is not provided in the options either.
Neither of the options given for either question is correct.
