Solution:

Given the cube below:

The net of the cube is shown below:

The area of each square face is

$\begin{gathered} area\text{ of square = L}^2 \\ =2^2 \\ =4\text{ ft}^2 \end{gathered}$

Since there are 6 square faces in the net, the surface area of the cube becomes

$\begin{gathered} 6*4\text{ ft}^2 \\ =24\text{ ft}^2 \end{gathered}$

Hence, using a net, the surface area of the cube is

$24\text{ ft}^2$
