$\Large\bold\star\green{\boxed{\underline{Solution:-}}}$

:$\Longrightarrow$ The answer is 4800cm².

$\large\bold\star\purple{\boxed{\underline{Explanation:-}}}$

:$\Longrightarrow$ Given:-

:$\Longrightarrow$ L = 80cm, B = 40cm, H = 20cm.

:$\Longrightarrow$ Therefore,

:$\Longrightarrow$ T.S.A = 2(lb + bh + hl)

:$\Longrightarrow$ = 2(80 × 40 + 40 × 20 + 80 × 20)

:$\Longrightarrow$ = 11200cm².

:$\Longrightarrow$ L.S.A = 2(l + b)h

:$\Longrightarrow$ = 2(80 + 40)20

:$\Longrightarrow$ = 4800cm².
