A suitcase with measures 80 cm x 48 cm x 24 cm is to be covered with a tarpaulin cloth. How many meters of tarpaulin of width 96 cm is required to cover 100 such suitcases?

Given: Length of suitcase box (l) = 80 cm,
Breadth of suitcase box (b) = 48 cm
And Height of cuboidal box (h) = 24 cm
∴ Total surface area of suitcase box = 2(lb+bh+hl)
= 2 (80 x 48 + 48 x 24 + 24 x 80)
= 2 (3840 + 1152 + 1920)
= 2 x 6912 = 13824 cm²
Area of Tarpaulin cloth = Surface area of suitcase
⇒ lxb = 13824
⇒ lx96 = 13824
⇒ l= 13824×96=144cm
Required tarpaulin for 100 suitcases = 144 x 100 = 14400 cm = 144 m
Hence, the tarpaulin cloth required to cover 100 suitcases is 144 m.
