The answer is 588 students , because you must make proportions.

You're welcome ;)
292in^3
3x6x10=180 because I’ve split the shape in half
7x4x4=112
180+112=292
The answer is 56! How you do this, is you take 80, and you multiply it by 7. Then you divide that answer by 10. Then you have your answer! I’m really bad at math but I do know how to do that!
(9 × 10) + (20x + 21) = 571
90 + 20x + 21 = 571
111 + 20x = 571
- 111
20x = 460
÷ 20
x = 23
I hope this helps!
