Answer 2

Answer:

The sum of length of edges of cube is 120 cm.

Step-by-step explanation:

Given  

One side of cube = 40 cm.

We need to find the sum of length of its edges?

Follow the below steps to find the solution.

Step 1:

As we know the edge of one side =4

Perimeter of one side of cube=40 cm

Length of one edge = 40/ 4

Length of one edge = 10 cm.

Step 2:

As we know, the cube has 12 edges  

Step 3:

Sum of length of edges = Total number of edge x length of one edge.

Sum of the length of its edges = 12 x 10

Multiply the two values which gives 120.  

Step 4:

Finally we got the sum of length of edges of cube is 120 cm.
