SAFF (Students against Fatty Food) is a group of students who are protesting the food in high school cafeterias. At a recent rally, the students covered the first 40 yards by 40 yards of the football field. There were 24 students in each 8 feet by 8 feet square. How many students were present at the rally?

Answer 1

The total area covered by students is 40 yd x 40 yd = 1600 yd^2

 

24 students covered 8 ft x 8ft  or (8 ft x 1 yd/3 ft)^2 = [(8/3) yard]^2 = (64/9) yd^2

 

Therefore, you need the amount of students per yard or 24 students/(64/9) yd^2

 

and multiply (students/yd^2)  x  (area covered by students) = number of total students present

 

Therefore:   number of students present = 24 students/(64/9) yd^2 x 1600 yd^2 = 5400 students
