Answer :
Final answer:
The nominal dimension of a 2x6 piece of lumber is 2 inches by 6 inches, while the actual dimension is approximately 1.5 inches by 5.5 inches. For the conversion, vertical studs placed 16.0 inches apart are equivalent to 40.64 centimeters apart when converted from inches to centimeters using the standard conversion factor.
Explanation:
The nominal dimension of a wood 2x6 refers to its name as used in the market, which is not its actual, physical measurement. This kind of lumber has nominal dimensions of 2 inches by 6 inches. However, the actual size will be slightly less due to the material being planed down for smoothness. The standard actual size of a 2x6 is about 1.5 inches by 5.5 inches.
In regards to question (b), placing vertical studs 16.0 inches apart is a common practice. To convert this distance into centimeters, we use the conversion factor that 1 inch equals 2.54 centimeters. Thus, 16 inches times 2.54 centimeters per inch equals 40.64 centimeters apart.
