Final answer:
The approximate surface area of a regulation basketball court can be estimated using mental math and fundamental units by equating the court to the length of 15 average males by the width of 7 average males, resulting in an approximation of 420 m².
Step-by-step explanation:
To approximate the surface area of a regulation basketball court using mental math and understanding of fundamental units, we can use a simple estimation technique. One could estimate that an average male is about 2 meters tall, and it might take about 15 such males laid out end to end to cover the length of the court, and approximately 7 to cover the width. Multiplying these estimates together, the approximate area of the basketball court can be calculated as 15 males x 2 meters/male x 7 males x 2 meters/male, which equals 420 m².
