Answer 3

hint:
if \(p\) is the perimeter of base, then the base area \(A_b\) and the lateral area \(A_l\), are:
\[\begin{gathered}
{A_b} = 2 \times \frac{{p \times k}}{2} \hfill \\
\hfill \\
{A_l} = 6 \times p \hfill \\
\end{gathered} \]
so, total area \(A_t\), is:
\[{A_t} = {A_b} + {A_l}=...\]

Answer 4

So would it be 120+20K?

Answer 5

Yes
