North Carolina Building Contractor License Practice Exam

For every 24 inches of wall area, how many metal tiles are required?

1. One

2. Two

3. Three

4. Four

The correct answer is: One

The correct answer is based on understanding how metal tiles are typically sold and applied. When determining the number of metal tiles required for a specific area, it is essential to know the coverage area provided by each tile. In this context, assuming that each metal tile has a coverage area of 24 square inches, it follows logically that one tile would be needed for every 24 inches of wall area. This relationship establishes a straightforward calculation where you divide the total wall area by the coverage area per tile. If you have a wall area of 24 inches, you would indeed need only one tile to cover that space completely. Understanding coverage is crucial in construction and contracting because it directly impacts material costs and waste management. For larger areas, more complex calculations may be needed, considering waste and cuts, but for the specific question regarding 24 inches of wall area, one tile suffices. Therefore, knowing the coverage of tiles helps in efficient project planning and execution in building practices.
