2.    A suitcase with measures 80 cm \times 48 cm \times 24 cm is to be covered with a tarpaulin cloth. How many metres of tarpaulin of width 96 cm is required over 100 such suitcases?

Answers (1)

Surface area of suitcase    = 2(80\times48+48\times24+24\times80) = 13824\ cm^2.

Area of such 100 suitcase will be 1382400\ cm^2

So lenght of tarpaulin cloth   = \frac{1382400\ cm^2 }{96\ cm} = 14400\ cm\ or\ 144m
