Final answer:
You should calculate 0.75 studs for every lineal foot of wall with studs spaced 16 inches on center. 16 inches converts to 40.64 centimeters.
Step-by-step explanation:
For exterior walls with studs spaced at 16 inches on center, you should figure 0.75 studs for every lineal foot of wall.
In other words, since 16 inches is 1.333 feet, and a wall has studs every 16 inches, you would have three studs for every 4 feet (which is 48 inches), resulting in a measurement of one stud per every 1.333 feet. This calculation simplifies to approximately 0.75 studs per lineal foot. When converting 16 inches to centimeters, the distance is 40.64 cm (since 1 inch equals 2.54 cm).
