If you have 500 cm2 of material available to cover different shapes. what is the maximum volume of each object that you could make with this amount of material?

You will get the maximum volume in the case of a sphere. You can use the formula for the surface of a sphere to calculate the radius; from there, you can calculate the corresponding volume.Similarly, for other objects, such as a cube, the volume you get will be less.
