For cuboid,
length (l) = 12+12+12 = 36cm
Breath (b) = 12cm
height (h) = 12cm
T.S.A of cuboid = 2(lb+bh+hl)
= 2(36×12+12×12+12×36)
= 2(432+144+432)
= 2×1008 = 2016 square cm
length (l) = 12+12+12 = 36cm
Breath (b) = 12cm
height (h) = 12cm
T.S.A of cuboid = 2(lb+bh+hl)
= 2(36×12+12×12+12×36)
= 2(432+144+432)
= 2×1008 = 2016 square cm

Step-by-step explanation:
l=12×3=36
b=12
h=12
surface area=2(lb+bh+hl
=2(36×12+12×12+12×36)
=2016cm^2
