A shipping container is in the shape of a right rectangular prism with a length of 13 feet, a width of 15 feet, and a height of 10 feet. The container is completely filled with
contents that weigh, on average, 0.39 pound per cubic foot. What is the weight of the
contents in the container, to the nearest pound?

Weight of contents in container = 102 pounds

A shipping container is in the shape of a Right rectangular prism with the length of the 12 feet away the 8.5 feet and the height of 4 feet. The container is completely filled with contents that weigh on average 0.25 pounds per cubic foot what is the weight in pounds of the contents in the container
Right rectangular prism is a cuboid
Volume of Right rectangular prism = 12 * 8.5 * 4 = 408 cubic feet
Content Density = 0.25 pounds per cubic foot
Density = Mass / Volume
=> 0.25 = Weight of contents in container / Volume of container
=> 0.25 = Weight of contents in container / 408
=> Weight of contents in container = 0.25 * 408
=> Weight of contents in container = 102 pounds
