How many lavatories are needed for the female occupants, according to calculations?

To determine the correct number of lavatories needed for female occupants, it is essential to consider the general guidelines set forth in building codes and regulations, such as the International Building Code (IBC) or local standards. Typically, the number of required fixtures is based on the total occupants or users of a specific space.

As the number of occupants increases, there is a proportional increase in the number of required lavatories to ensure adequate provision for women, preventing long wait times and providing convenience. Often, building codes will specify a ratio, such as one lavatory for a certain number of female occupants (for example, one lavatory for every 50 females).

In this case, if the calculated need is for three lavatories to accommodate the specified number of female occupants, this aligns with typical standards for ensuring sufficient restroom facilities. This account takes into consideration not only comfort and accessibility but also legal compliance with occupancy standards. Thus, the answer of three lavatories meets the appropriate guidelines for the number of female occupants specified in the question.
