Question

a suitcase with measure 80cm×24cm×48cm is to covered with tarpaulin cloth . how many meters of tarpaulin of width is required to cover 100 such suitcases

Answer 1

TSA of tarpaulin cloth which is required to cover one suitcase
= 2(80×24+24×48+48×80)
= 2×3200
= 6400cm^2

Now width of the tarpaulin cloth is given as 90cm
let the length of the cloth be l
area of the cloth 6400cm^2
=> 6400= l × 90
=> l = 6400
-------
90
=> l = 71.11...………
=> l = 71.1cm (approx.)

therefore length of the tarpaulin cloth required to for one suitcase is 71.111cm(approx.)
length of the tarpaulin cloth required for 100 such suitcase= 100×71.111
= 7111.1cm(approx.)
= 71.1m (approx.)
