(2) A suitcase with measures 80 cm 48 cm 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?
Ans. Given: Length of suitcase box = 80 cm, Breadth of suitcase box = 48 cm
And Height of cuboidal box = 24 cm
Total surface area of suitcase box
=
= 2 (80 48 + 48 24 + 24 80)
= 2 (3840 + 1152 + 1920)
= 2 6912 = 13824
Area of Tarpaulin cloth = Surface area of suitcase
= 13824
= 144 cm
Required tarpaulin for 100 suitcases
= 144 100 = 14400 cm = 144 m
Hence tarpaulin cloth required to cover 100 suitcases is 144
