Final answer:
The maximum distance between the last two rafters when laying them out should not exceed 24 inches for standard building practice. The 16-inch spacing commonly used for vertical studs translates to roughly 40.64 centimeters.
Step-by-step explanation:
When laying out rafters, the distance between the last two may be less than 24 inches but should not be more than 24 inches according to typical building codes and practices. For standard spacing of rafters or floor joists, 24 inches is a common on-center distance, which helps ensure structural integrity, allowing the roof to support typical loads. When converting distances for construction materials, such as vertical studs that are typically 16 inches apart, to metric measurements, 16 inches is equivalent to approximately 40.64 centimeters.
