Answer: The gross weight is 225 lb.
Step-by-step explanation:
Since we have given that
Weight of an article 10 lb
Weight of box = [tex]\frac{1}{2}\ lb[/tex]
Number of article = 20
Weight of one freight container = 15 lb
So, Total weight of article is given by
[tex]\text{Number of articles }\times \text{Weight of each article}\\\\=20\times 10\\\\=200\ lb[/tex]
Total weight of box becomes after 20 articles are put into it .
[tex]20\times \frac{1}{2}\\\\=10\ lb[/tex]
Gross weight is given by
[tex]200+10+15\\\\=225\ lb[/tex]
Hence, the gross weight is 225 lb.
