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?

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

= 2(80 × 48 + 80 × 24 + 48 × 24)

= 13824 cm²

Hence surface area of 100 such suitcases = 1382400 cm²

Required tarpaulin = surface area of 100 such suitcases

So, required length =

= 14400 cm or 144 m
