Answer 1

Answer:

A suitcase is in the shape of a cuboid

So, surface area of a cuboid=2(lb+bh+lh),where l=length, b=breadth, h=height of the cuboid

Let the length, breadth and height of the suitcase be l , b, h respectively

Here, l=80cm , b=40cm , h=24cm

Therefore, area=2(80*40+40*24+80*24)cm²

=2(3200+960+1920)cm²

=2*6080cm²

=12160cm²

Hence, surface area of 100 suitcases= 12160cm²*100

=1216000cm²

Also, surface area of the tarpaulin will also be the same

Therefore,required length of tarpaulin

=surface area÷width

=1216000cm²÷90cm

=13511.11111111111cm (approx)

=13.16 m
