Presents the formula and an example showing how to find the cross-sectional area of a cylinder. In this case, it is the same as the surface area for the circular faces.

Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box...

This activity allows the user to find the volume and surface area of various functions as they are rotated around axes. This applet can be used to practice finding integrals using the disk and washer methods of calculating volume.

This calculator finds the volume, surface area, and height of a triangular prism. Surface area calculations include top, bottom, lateral sides, and total surface area. Height is calculated from a known volume or lateral surface.

The career of hydrologist could become more and more important as the use of water increases. Find out about the education needed to become a hydrologist and read the Science Buddies profile about the many areas hydrologists use their...

Why can't cells continue to grow larger and larger to become giant cells, like a blob? Why are most cells microscopic in size? Find out answers to these questions through this "hands-on" activity that simulates the changing relationship...

Find out the effect that hard, dark surfaces like streets, parking lots and rooftops that trap and hold heat have on cities and urban areas.
