Take a piece of letter-sized paper and tape the short ends to make a tube. Label this tube **A**.

Take another piece of letter-sized paper and tape the long ends to make another tube. Label this tube **B**.

Place each tube on a flat surface, so that they stand up on end.

Using the formula for the volume of a cylinder, find out which tube will hold more stuff (like popcorn or candy)?

Hints:

Letter-sized paper is 8.5 inches wide by 11 inches tall.

To find the radius of each tube, use the circumference formula, C = 2πr
