The amount of space taken up by something is called ____________.
volume
200
Which cube is experiencing the most pressure, and why?
Cube 3, because pressure depends on depth, the deeper you are the more pressure you will experience. Due to cube 3 being the deepest cube, it is experiencing the most pressure when compared to the other cubes.

Here are 3 containers of the same fluid (with the same density). Which container has the least pressure at the bottom of the container, and why?
Considering all 3 containers have the same amount of liquid, they will all have the same amount of pressure at the bottom.
