Answer:
The school can build 2640 clasrooms theorethicly that are 4 feet apart,
but if each clasroom is next to another one that means it is separated by 2 walls then it would be 1320 classrooms
Explanation:
2 x 5280 = 10560
10560/4 = 2640
And if the clasroom on each side has to be seperated by walls then
10560 /8= 1320
