Question

in a cuboid if length is 18 cm , breadth is 6 cm , height is 6 cm find its surface area​

Answer 1

Here given,

$l = 18cm$

$b = 6cm$

$h = 6cm$

Surface are of a cuboid

$= 2(lb + bh + hl)$

2[(18×6) + (6×6) + (6×18)]

=2[108 + 36 + 108]

= 2 × 252

=504cm^2

Answer 2

Answer ->

Given,

Length = 18cm

Breadth = 6cm

Height = 6cm

Now,

Surface are of a cuboid

= 2(lb + bh + lh)

= 2[18×6 + 6×6 + 6×18 ]

=2[108 + 36 + 108]

= 2 × 252

=504cm^2
