Step-by-step explanation:
a cube.
that means all the sides are equally long.
and the volume of the cube is simply
side³ = 216 cm³
side = 6 cm
such a cube has 12 side edges :
4 for the square on the floor,
4 for the square on the top,
4 in the middle around it.
12×6 = 72 cm
so, there are 100-72 = 28 cm of wire left (after creating the cube).
