faces and all of them are identical squares. The length of an edge of the cube is
given by a. Find the formula for the total length of the edges of a cube.​

Answer 1

Answer:

A cube is a three-dimensional figure as shown in figure alongside. It has six faces and all of them are identical squares. The length of an edge of the cube is given by a.

The formula for the total length of the edges of a cube,

$= 12 \times a$

Answer 2

Solution :-

Since all the edges of a cube are of same length, say, $l.$ Then, their total length = $12 × l$
