Final answer:
The question pertains to the appropriate span length for floor joists given a load specification and joist size on a construction site. Without the referenced table for maximum joist spans, we cannot provide a definitive answer; such a table would indicate the correct span length based on the material's strength and the load it must bear.
Step-by-step explanation:
The question relates to the maximum joist spans for a construction project. In the context of a construction site, specifically when remodeling a house, workers need to know how far apart they can place the joists that support the floors or ceilings. When dealing with a load of 30 pounds per square foot (PSF) and using 2 x 8 boards with a joist spacing of 16 inches, reference to a standard table for maximum joist spans is required. These tables are typically based on building codes and standards that take into account material strength, spacing, and the load that the joists are expected to carry.
While the question does not provide a table, in practice, builders refer to such tables to determine that the appropriate span length. Assuming that a reputable source recommends a maximum span length among the options provided, builders should choose the span length that complies with those guidelines and assures safety and structural integrity. Unfortunately, with the data provided, we cannot ascertain a definitive answer without the table referenced in the question. In a real-world scenario, one must consult the specific table or guideline in use to find the correct span for the given variables.
