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

Answer 1

Total surface area of suitcase= 2(lb+bh+lh) = 2(80*48+48*24+80*24) = 2(3840+1152+1920)= 13824 cm^2

Surface area of 100 suitcase= 100*13824 cm^2 = 1382400 cm^2

Area of tarpaulin = lenght*breadth

1382400=lenght*96

lenght=14400 cm
