Question

The surface area of cuboid-shaped box having length=60 cm, breadth=50cm and height=30cm is​

Answer 1

Answer:

Given,

l=60cm,b=50cm and h=30cm

Now,

T.S.A(Total surface area) of the cuboid

=2(lb+bh+hl)

=2(60×50 + 50×30 + 30×60)

=2(3000+1500+1800)

=2×6300

=12600 cm square

and C.S.A(Curved surface area) of the cuboid

=2(l+b)×h

=2(60+50)×30

=2×110×30

=220×30

=6600 cm square
