A cube is a three-dimensional figure as shown in figure. It has six faces and all of them are identical squares. The length of an edge of the cube is given by
. Find the formula for the total length of the edges of a cube.
Answer:
It is given to us that length of every edge of a cube
Perimeter of each square face
There are 6 faces in a cube. Therefore, perimeter of all the 6 faces
Note that each edge has been counted twice when we calculated perimeter of all 6 faces. Therefore, total length of all the edges of a cube
