Solution

Length of edge = l

Number of edges = 12

Total length of the edges = Number of edges × Length of one edge

= 12l

Length of edge = l Number of edges = 12 Total length of the edges = Number of edges × Length of one edge = 12l

Length of edge = l

Number of edges = 12

Total length of the edges = Number of edges × Length of one edge

= 12l
