Question

the length breadth and height of a cuboid are 4m 3m and 2m respectively then surface area of cuboid will be

Answer 1

Hey friend..!!! here's your answer
_________________________

Length ==> 4m
Breadth => 3m
Height ==> 2m

Surface area of cuboid ==> 2(lb + bh + hl)

= 2(4×3 + 3×2 + 2×4) m^2
= 2(12 + 6 +8) m^2
= 2(26) m^2
= 52 m^2

So that the surface area of cuboid is 52 m^2

Answer 2

Given,
l = 4m
b = 3m
h = 2m


Lateral surface area of Cuboid = 2 (bh + hl)
= 2 [ (3×2) + (2×4) ]
= 2 ( 6 + 8)
= 2 (14)
= 28 m^2

Total surface area of cuboid = 2 ( lb + bh + hl)
= 2 [ (4×3) + (3×2) + (2×4) ]
= 2 [ 12 + 6 + 8]
= 2 [26]
= 52 m^2


Hope it helps.
