a box measures 80cm*48cm*24cm.is to be covered with a plastic sheet how many metres of sheet of width 96cm is required to cover 50 such boxes?
Answers
Breadth = 48 cm
Height = 24 cm
Total Surface area of 1 suitcase = 2LB + 2BH + 2HL
= 2(80)(48) + 2(48)(24) + 2(24)(80)
= 7680 + 2304 + 3840
= 13824
Total surface area of 50 suitcases = 13824 * 50
= 691200
Length of Plastic sheet required = 691200 / 96
= 7200
= 7200 / 100 (1 m=100 cm)
= 72 m
