Answer:
36 on a surface edge
6 on a corner edge length or width.
Step-by-step explanation:
As this is a cube each dimension has to be equal.
so the answer simply is square root the area.
√216 = 6 √6
We double check
6^2x6 = 36 x 6 then complete the cube 36 x 6 = 216
Rectangles are much different when working out lengths as whatever is workable in multiplication across and down shows different results.
An edge of a single cube means the surface similar to cross section.
So there are 6 on a line , we multiply this by 6 and find 36 on a single surface.
There are 6 on the corner edge.
