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 100 such suitcases?

Given: →l × b × h = 80 × 48 × 24 →B = 96cm →T.S.A = 2[(l × b) + (b × h) + (l × l)] →T.S.A = 2[(80 × 48) + (48 × 24) + (24 × 80)] = 13824 sq cm →T.S.A of 100 suitcases = 13824 × 100 = 1382400 sq cm →Length of tarpaulin = 1382400/B →Length of tarpaulin = 1382400/96 = 14400 cm = 144 m
