Side = 2.1m

Lateral surface area =

\begin{gathered}4 {l}^{2} \\ \\ = 4 \times 2.1 \times 2.1 \\ = 17.64 {m}^{2} \end{gathered}

4l

=4×2.1×2.1

=17.64m

Now,

Total surface area =

\begin{gathered}6 {l}^{2} \\ \\ = 6 \times 2.1 \times 2.1 \\ = 26.46 {m}^{2} \end{gathered}

6l

=6×2.1×2.1

=26.46m
