Someone pls answer these questions as quick as possible. warning ⚠️ = no silly answers. don’t answer if you’re not sure too.

Let's do the unit cube and worry about the side length later.

Let's assign F(0,0,0), H(1,1,0), A(0,1,1), C(1,0,1)

Let's call the beetle positions P and Q, functions of time t.

P = F + 2t(H-F) = tH = 2t(1,1,0) = (2t,2t,0)

Q = A + t(C-A) = (0,1,1)+t(1,-1,0)=(t, 1-t, 1)

The squared distance is
