A shipping container is in the shape of a right rectangular prism with a length of 2.5 feet, a width of 3 feet, and a height of 4 feet. The container is completely filled with contents that weigh, on average, 0.66 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

++x%5e2+=+1296%2f2+=+648+
