Q. 24.2( 247 Votes )

A suitcase with measures 80 cm × 48 cm × 24 cm is to be covered with a tarpaulin cloth. How many metres of tarpaulin of width 96 cm is required to cover 100 such suitcases?

Answer :

Length of suitcase = 80 cm
Breadth of suitcase = 48 cm
Height of suitcase = 24 cm

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

= 2(80 × 48 + 80 × 24 + 48 × 24)

= 13824 cm2

Area of cloth = Area of suitcase.
Hence surface area of 100 such suitcases = 1382400 cm2

Required tarpaulin = surface area of 100 such suitcases

So, required length =

= 144 cm

Required tarpaulin for 100 suitcases = 144 x 100 = 14400 cm = 144 m 

Hence, the tarpaulin cloth required to cover 100 suitcases is 144 m.​
