From a piece of wire, you need to make the frames of a triangular pyramid and a cube. Which edge of these figures is 10 cm. How long should you take the wire for making each figure?

The problem is apparently about a regular triangular pyramid. A regular pyramid has six identical edges. Wire will need 6 * 10 = 60 cm.
A cube is a special case of a rectangular parallelepiped. The cube has 12 identical edges. Wire length 12 * 10 = 120 cm.
