I think that this is a combination problem. From the given, the 8 students are taken 3 at a time. This can be solved through using the formula of combination which is C(n,r) = n!/(n-r)!r!. In this case, n is 8 while r is 3. Hence, upon substitution of the values, we have
C(8,3) = 8!/(8-3)!3!
C(8,3) = 56
There are 56 3-person teams that can be formed from the 8 students.
It could be a building with a triangular top. If the building had a triangular top, then it must have 3 rectangles as its sides. So your answer would be, a building with a triangular top.
30 should be the correct answer
