A wall is 35' long and utilizes 2" x 4" x 8' studs. How many studs are needed using 16" OC spacing?

To determine the number of studs needed for a wall that is 35 feet long with 2" x 4" x 8' studs placed 16 inches on center (OC), it is essential to convert all measurements into the same units first.

The wall length of 35 feet equates to 420 inches (as there are 12 inches in a foot, 35 feet x 12 inches/foot = 420 inches).

Next, calculate the spacing needed for the studs. Since the studs are spaced 16 inches apart, you can divide the total length of the wall by the spacing. However, you also need to account for the fact that you need a stud at the end of the wall as well.

The formula to find the total number of spaces between the studs is:

Number of Spaces = (Total Length / Space Between Studs) + 1

Using the wall length of 420 inches:

420 inches / 16 inches = 26.25

Since you need whole studs, and you need an additional stud at the end of the wall, round up to account for that from the whole number of spaces:

26.25 rounds to 26, but adding 1 for the additional stud gives a
