Hi, thank you for posting your question here at Brainly.

To solve this problem, first you must form an equation. In this case,

Vpyramid = n*Vcube, which means the total volume of the pyramid is equal to the volume of the total number of cubes deposited by "n" students.

Vpyramid = 1/3*base*height = 1/3*12^2*17 = 816 ft3
Vcube = s^3 =  1 ft3

Hence, 816 = n(1), then n = 816 students.

Therefore, about 800 students are present in the school.
