Answer 2

Answer:

96 cm.

Step-by-step explanation:

Four making a square on one surface, four making a square on the opposite surface, and another four connecting the corresponding corners of those two surfaces. 4 + 4 + 4 = 12 edges total.

Now, you say each of those edges is 8 cm: 12 edges, and 8 cm per edge.

length of wire needed = 12 * 8 = 96 cm

i hope this answer helps you.

generally there is no perfect formula for perimeter of a cube.
