[SOLVED] Aluminum Boats and Buoyancy. All right, here we go. I'm stuck doing a "Lab Practicum" which has this specific task: Build a boat out of aluminum foil alone. Find the maximum about of mass it can hold without tearing, capsizing, or just plain submersing into a bucket of water. The piece of foil is 30cm by 30cm. That last bit of information is probably unnecessary because I already designed the boat. It's the way that I find that mystery mass that's got me hung up. Thanks so much for the help.
