Question

Two cubes each of side 6 cm are placed together. Find the surface area of the cuboid thus formed

Answer 1

Step-by-step explanation:

Given,

By joining two cubes of each side of 6 cm end to end, we get a cuboid whose,

Length ⇒ (6 + 6 ) cm ⇒ 12 cm

Breadth ⇒ 6 cm

Height ⇒ 6 cm

Now , as we know that :

Surface are of cuboid= 2(lb+lh+bh)

Substituting values,

=2(12×6)+(12×6)+(6×6)cm

2

=2(72+72+36)cm

2

=2(180)cm

2

⇢T.S.A

(Cuboid)

=360cm

2

Hence, total surface area is ={ 360 \: {cm}^{2} }360cm
