b) What is the smallest number of times it will be necessary to break the wire in order to still produce the required frame?
a) What is the minimum number of pieces of wire needed in order to weld a cube’s frame?
b) What is the maximum length of a piece of wire that can be cut from this frame? (The length of the edge of the cube is 1 cm).
