This is how the pattern goes:
Deku would try to solve the cube, ask the dekusquad to help him solve it, then cry over it when he can't
Bakugou would try to solve the cube and destroy it out of frustration
Todoroki might accidentally burn the cube, but he'll probably give it to someone else before he can
Mineta would try to solve the cube and cry over it when he can't, then he'll accept it as it is
Denki would eat the cube and ask it to solve itself
Uraraka would give the cube to Deku, who would cry over it
Jirou would give the cube to Momo
Tokoyami would accept the cube as it is
BTW: Mineta is actually really smart, that's a fact
