You will perform a simple experiment to examine how the volume of a three-dimensional object changes if you slant its vertical axis. You can perform this activity using a stack of identical coins, CDs, or any available set of identical disk-shaped objects. If you cannot locate a set of disk-shaped objects, go to oblique cylinders to simulate the experiment online. Scroll down to the Volume section. Begin by stacking the disks one on top of the other so they create an upright stack. That is, the disks should form a right cylinder.

Question 1
Think about the volume of the stack. By definition, what is the volume of the stack equal to? Express you answer in words instead of numbers.
