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?

Length of suitcase box, l = 80 cm, 

Breadth of suitcase box, b= 48 cm 

Height of cuboidal box , h = 24 cm 

Total surface area of suitcase box$= 2(lb+bh+hl)$

$= 2(80\times 48+48\times 24+24\times 80)$

$= 2 (3840+1152+1920)$$= 2\times 6912 = 13824 c{m}^2$

Area of Tarpaulin cloth = Surface area of suitcase

$l \times b= 13824$

$l \times 96 = 13824$

$l = 144$

∴, Required tarpaulin for 100 suitcases $= 144\times 100 = 14400 cm = 144 m$
