The area that covers the outside of a figure is its surface area. Surface area can be compared to wrapping a present or covering the outside of the object with paper.
The interactive tool at Annenbeg's web page shows how to find the surface area of cylinders and prisms. The surface area is the sum of 2 ends of the cylinder and the middle section.
Middle= Circumference * height + Ends (2 * Area)
Which container below has the greater surface area, and how much more area?
How would you verify and make sure that both containers have a volume of 750ml?
