Question

Anyone please help!!!!!!!!!!!!

Answer 1

well, lateral area means only the area of the sides, namely just the four triangular faces.

`\bf \textit{area of an equilateral triangle}\\\\ A=\cfrac{s^2√(3)}{4}~~ \begin{cases} s=sides\\ \cline{1-1} s=8 \end{cases}\implies A=\cfrac{8^2√(3)}{4}\implies A=16√(3) \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{area of the 4 triangles}}{4(16√(3))}\implies 64√(3)`
