Question

This cube has six faces and all of them are identical squares.If $x$ is the length of an edge of the cube, find the formula for the total length of all the edges of the cube.

Answer 1

According to the question,

Edge length of a cube $=x$

We know that the formula for total length of all the edges of the cube $=12\times$one edge length

Hence,the formula for the total length of all the edges of the cube $$\begin{gathered} =12\times x \\ =12x \end{gathered}$$
