A sheet of paper has the shape of a rectangle with a length of 30 cm and a width of 20 cm.
Roll the sheet into a cylinder so that the shorter side is the height of the cylinder. Calculate the area of the resulting cylinder.
Let the sheet be transformed into a regular 4-sided prism with a height equal to the length of the shorter side. Calculate the surface area of the prism.
By what percentage is the area of the cylinder larger than the area of the prism?
