Final answer:
The actual size of 1x3 lumber is 1 inch thick and 3 inches wide. The distance of 16.0 inches is equal to 40.64 centimeters.
Step-by-step explanation:
1x3 lumber refers to a piece of wood that is 1 inch thick and 3 inches wide. Lumber sizes are designated in this format, with the first number representing the thickness and the second number representing the width. However, the actual size of a 1x3 piece of lumber may vary slightly due to milling and drying processes. It is important to note that the nominal size does not necessarily match the actual size of the lumber.
In order to convert the distance of 16.0 inches to centimeters, we can use the conversion factor that 1 inch is equal to 2.54 centimeters. By multiplying 16.0 inches by 2.54 centimeters/inch, we get 40.64 centimeters.
