1. Find an empty box. Measure and record its length, width, and height. 2. Cut the box apart to reveal its 6 rectangular faces. Take a picture of the newly-created net. 3. Upload your picture to Seesaw and use your length, width, and height measurements to label the area of all 6 faces. 4. Add the areas of all 6 faces (or use a shortcut: add the areas of the 3 different faces, then double the sum) to find the total surface area. Record the total surface area somewhere on your picture.
