Given :-

Side of cube = 15m

To find :-

Longest pole = ?

$\small \sf {\orange{\underline {\green {\underline { Solution ᭄ \ :- }}}}}$

Longest pole means using the formula of diagonal of cube .

$\begin{gathered}\dag\;{\underline{\frak{As\;we\;know\;that,}}}\end{gathered}$

Diagonal of cube = √3a

where , a = side of cube.

$\begin{gathered}\dag\;{\underline{\frak{Putting\:values\:in\:formula,}}}\end{gathered}$

Diagonal of cube = √3 x 15

⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀= 15√3 or 25.95m

$\sf{⤗ \ 15√3 \ or \ 25.95m}$

Therefore , the longest pole that can be placed will be of 15√3 m.
