A cubical box with lid has a length of 30 cm. Find the cost of painting the inside and outside of the box at 5.50 per m².

${ \huge{ \fcolorbox{green}{blue}{ \fcolorbox{red}{teal}{☆Âň§wəř☆}}}}$

$\blue{side \: of \: cubical \: box \: = 30cm = 0.3m}$

$\red{Area \: to \: be \: painted = 6 {l}^{2} }$

$\purple{ = 2 \times 6 \times ( {0.3})^{2}}$

$\green{ = 1.8 {m}^{2} }$

$\pink{cost \: of \: painting \: inside \: and \: outside \: of \: cubical \: box}$

$\blue{ = ₹(1.8 \times 5.50)}$

$\red{ = ₹5.94}$
