How does surface area affect floating? - Answers

Surface area affects floating by influencing the buoyant force acting on an object. A larger surface area increases the amount of water displaced when an object is placed on it, enhancing buoyancy. This is why some objects, like wide boats, can float even if they are heavy; their broad surface area allows them to displace enough water to counteract their weight. Conversely, a small surface area may not displace sufficient water to achieve buoyancy, causing the object to sink.
