We start by calculating the volume of the right rectangular prism which is;
[tex]\begin{gathered} v=l\times h\times w \\ v=5.5\times7.5\times12 \\ v=495ft^3 \\ \text{The container is completely filled with contents that weigh 0.75 pounds } \\ \text{per cubic foot. This means;} \\ \text{Each cubic foot would contain;} \\ \text{Weight of contents=}495\times0.75 \\ \text{Weight}=371.25 \\ \text{Weight}\approx371 \end{gathered}[/tex]The weight of the contents in the container therefore is 371 pounds (to the nearest pound).
