 Question 172526: I am studying surface area and am totally stuck. My problem reads: "A rectangular metal container with an open top is fabricated from 0.072-inch think aluminum sheet. The container is 18.00 inches wide, 25.00 inches long, and 23.00 inches high. The aluminum sheet weighs 1.045 pounds per square foot. Find the total weight of the container." I know how to get the lateral area (which would be 1,978 square inches) and the surface area (which would be 2,428 square inches), but I do not know how to go about finding the weight from the information I have. I tried multiplying the surface area by the the thickness of the metal, but that made cubic units and I need square feet. What do I do to find the answer to this problem?
