There are 40 students playing dodge ball in a high school gym that is 100 feet long by 60 feet wide. There are 12,000 balls available in the gym to throw. What is the population density of the balls in the gym (balls per square foot)?

2 balls/ft²

Step-by-step explanation:

The area of the gym is:

A = (100 ft) (60 ft)

A = 6,000 ft²

The population density is:

D = 12,000 balls / 6,000 ft²

D = 2 balls/ft²

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
