How do you calculate the boat capacity based on its dimensions?

The capacity of a boat is primarily determined by its dimensions, particularly length and width. The formula that uses boat length and width involves multiplying these two measurements and then dividing by a specific factor that accounts for safety and stability.

In this case, multiplying the boat length by the boat width and then dividing by 15 is a widely accepted method for estimating the number of people a boat can safely carry. The factor of 15 is used to ensure that the calculation considers safety guidelines and stability concerns while providing a conservative estimate of capacity.

This method allows for adequate space per person, which is crucial for preventing overcrowding and ensuring the vessel's performance in the water. It complies with safety regulations to prevent capsizing and aids in maintaining balance and maneuverability of the boat.

The other options do not take into account the necessary safety factors or correct mathematical principles required for calculating boat capacity, which is why they would not yield an appropriate measure of how many individuals the boat can accommodate safely.
