Final answer:
The actual size of 1x10 lumber is typically 3/4 inch thick by 9 1/4 inches wide. Vertical studs are commonly spaced 16.0 inches apart, equivalent to 40.64 centimeters. Real measurements are vital for accurate and practical applications.
Step-by-step explanation:
The actual size of 1x10 lumber refers to its dimensions after it has been planed and finished, which are typically smaller than the nominal size designated by the '1x10' label. The nominal size is a label that indicates the size of the lumber when it is first cut, and before it is dried or planed, which shrinks the final size. For example, the actual size of 1x10 lumber is usually 3/4 inch thick and 9 1/4 inches wide.
Regarding the part of the question about vertical studs placement: vertical studs in construction are typically placed 16.0 inches apart, center to center. To convert this distance to centimeters, we use the conversion that 1 inch is equal to 2.54 centimeters. Therefore, 16.0 inches is equal to 16.0 x 2.54 cm, which equals 40.64 centimeters.
When we compute "real" measurements, we are seeking actual dimensions or quantities to inform our construction, engineering, or design choices, similar to when we need actual quantities for something practical like purchasing 10 t-shirts.
