For this item, all we have to identify is the area of the hanging light cover. Because it is said that it does not have a cover, we are only concerned about the lateral area which is equal to
Lateral area = 4(x)(l)/2 = 2xl
where x is the measure of the side of the square base and l is the length of the slant height.
After calculating the area in square foot, we multiply this to 2.45 pounds/ft², if the obtained value is ≤ 35 then, the chain can support the light cover.
