Answer 1

a.

Given:-

$l = 60$

$b = 40$

$h = 50$

Formula:-

$2(lb + bh + hl)$

$\huge\bigstar\underline\mathfrak{Answer}$

$area \: of \: cuboid = 2(lb + bh + hl)$

$= 2(60 \times 40 + 40 \times 50 + 50 \times 60)$

$= 2(2400 + 2000 + 3000)$

$= 2(7400)$

$= 14800m ^{2}$

b.

Given:-

$l = 50$

Formula:-

$6l ^{2}$

$\huge\bigstar\underline\mathfrak{Answer-}$

$area \: of \: cube \: = 6l ^{2}$

$= 6 \times 50 \times 50$

$= 300 \times 50$

$= 15000m^{2}$
