The surface area is 13630=1/2(4)(height)30=2(height)and from there we can solve. 30/2=15the height of the triangle is 15, which is also the slant heightto check our work, 1/2(4)(15)=304x15=601/2x60=30
There are 30 students. (: Becuase since 6 students make up 20% of the class. you just multiply 5 by 6 and get 30.
