Aquarium Surface Area Calculations

The video tutorial explains how to calculate the surface area of an open-top aquarium by summing the areas of its five rectangular faces: the bottom, two sides, and front and back. The process involves using the formula for the area of a rectangle (length times width) for each face and then adding these areas together. The tutorial provides step-by-step calculations for each face, resulting in a total surface area of 577 square centimeters.
