$\huge\mathfrak\red{Question❓}$

● Find the volume, lateral surface areas(LSA) and the total surface area (TSA) of a cuboid whose length = 12cm, breadth = 8m and height = 35cm?

$\huge\mathfrak\red{Answer \: ✔}$

● T.S.A = 1056cm^2

$\huge\mathcal\red{Step \: by \: step ⬇}$

Given that l=20cm, b=12cm, h=9cm

∴T.S.A=2(lb+bh+lh)

=2[(20×12)+(12×9)+(20×9)]

=2(240+108+180)

=2×528

∴T.S.A=1056cm^2
