Final answer:
The actual size of 2x6 lumber is 1.5 inches by 5.5 inches. The distance between vertical studs placed 16.0 inches apart is 40.64 centimeters.
Step-by-step explanation:
The actual size of 2x6 lumber is 1.5 inches by 5.5 inches. This means that when you purchase a piece of lumber labeled as 2x6, it will actually measure 1.5 inches in thickness and 5.5 inches in width.
To convert the distance between vertical studs from inches to centimeters, we can use the conversion factor of 2.54 centimeters per inch. So, if vertical studs are typically placed 16.0 inches apart, the distance in centimeters would be 16.0 inches x 2.54 centimeters/inch = 40.64 centimeters.
