One rule of thumb for estimating crowds is that each person occupies 360 square inches. Use this rule to estimate the crowd size of a section that is 20 feet deep by 20 feet wide of a parade route.

Answer 1

20 ft = 240 inches

240x240= 57600

57600/360= 5760/36= 1440/9= 160 people

20x20= 400ft^2 = 400x144 = 57600 in^2
