Andy is participating in this years science fair. He is testing how fast metal takes to rust. He rakes 3 pieces of iron one is a cube, and the other is a sheet both weighing the same. It takes the cube almost a week to fully rust but the sheet only takes 2 days. The only difference between the two is that the sheet has more surface area. He tries this again with a cylinder so the surface area is larger than the cube but smaller than the sheet and it takes about 4 days to fully rust. Which will rust faster given they contain the same amount of iron, a sheet or a cylinder?
