The document is a worksheet about finding the surface area of a rectangular cabinet. It asks the student to estimate the measurements of the cabinet and calculate the area of each side. The student finds the area of the front, back, top, bottom, left and right sides and adds them together to get the total surface area of 9072 in^2. The worksheet then asks if the student missed anything in their calculation.
