Given :
To Find :
Solution :
[tex]\longmapsto\tt{Length(l)=12m}[/tex]
[tex]\longmapsto\tt{Breadth(b)=5m}[/tex]
[tex]\longmapsto\tt{Height(h)=3m}[/tex]
Using Formula :
[tex]\tt\boxed{Surface\:Area\:of\:Cuboid=2(lb+bh+hl)-lb}[/tex]
Putting Values :
[tex]\longmapsto\tt{2(12\times{5}+{5}\times{3}+{3}\times{12}-(12\times{5}}[/tex]
[tex]\longmapsto\tt{2(60+15+36)-60)}[/tex]
[tex]\longmapsto\tt{2(111)-60}[/tex]
[tex]\longmapsto\tt{222-60}[/tex]
[tex]\longmapsto\tt\bold{324{m}^{2}}[/tex]
Now :
[tex]\longmapsto\tt{Cost\:of\:324{m}^{2}=324\times{3}}[/tex]
[tex]\longmapsto\tt\bold{Rs.972}[/tex]
