(There's an Algebra.com one too, but I am highly doubtful in its correctness) I, however, fail to grasp how/why a 2cm thick base implies every wall is 2 cm. Yes, I have never seen a box with a thicker base, but what if there's some styrofoam on the bottom? In short, why can we assume each wall is 2cm thick?\r
