Answer 2

${ \large{ \sf{ \underbrace{\underline{\bigstar \:Given :-}}}}}$

Dimensions of room - 8m × 6m × 4m

Cost of painting - Rs.80

${ \large{ \sf{ \underbrace{\underline{\bigstar \:Have \:to \:find :-}}}}}$

Area of room

Cost of painting

${ \large{ \sf{ \underbrace{\underline{\bigstar \:Let's\: do\: it :- }}}}}$

$\textbf\color{magenta}{Two walls area is 2 x 8 x 4}$

$\tt{= 64 sq. m.}$

$\textbf\color{magenta}{The area of other two walls 2 x 6 x 4}$

$\tt{= 48 sq. m.}$

$\textbf\color{magenta}{Total are to be painted = 64 + 48}$

$\tt{= 112 sq.}$

${ \large{ \boxed{ \red{ \underline{ \bf \:Cost\: of \:painting \:this \:area\: = \:rate\: x \:area}}}}}$

$\boxed{\bf{= 80\: x\: 112 \:=\: 8960 Rs.}}$
