Weight of empty box = 680 gram
Step-by-step explanation:
Given:
Number of noodle = 6 dozen = 12(6) = 72
Weight of each noodle in each packet = 175 gram
Weight of each packet = 10 gram
Total weight = 14 kg = 14,000 gram
Find:
Weight of empty box
Computation:
Total weight of noodle = 72(175) + 72(10)
Total weight of noodle = 13,320 gram
Weight of empty box = Total weight - Total weight of noodle
Weight of empty box = 14,000 - 13,320
Weight of empty box = 680 gram
