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
