Video Solution

Solution Steps

00:00 Calculate the sum of cube edges
00:03 An edge in a cube is a side of a face
00:06 Let's mark each edge in the cube with letter A and count
00:10 We have 12 equal edges in the cube
00:13 Let's substitute the edge value according to the given data and solve for the sum
00:21 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we will use the basic property of cubes regarding the number of edges and the length of each edge. Follow these detailed steps:

  • Step 1: Identify the length of each edge.
    The problem states that each edge of the cube is 2 cm long.

  • Step 2: Determine the number of edges in a cube.
    A cube has 12 edges.

  • Step 3: Calculate the total sum of the edge lengths.
    Multiply the number of edges by the length of each edge. Thus, the total edge length is given by: 12×2=24cm. 12 \times 2 = 24 \, \text{cm}.

Therefore, the sum of the cube's edges is 24 24 , cm.
