Here is the same partially filled rectangular prism.

You see that it measures a base of 9 unit cubes and you can see a height of 4 unit cubes. So why then is the volume greater than 36 unit cubes?

• Because 9 x 4 is greater than 36.

• It's not greater than 36. It's 27 unit cubes because the height is only 3 unit cubes.

• Because the height of the cubes doesn't go all the way to the top, so there's more than 36 cubic units.

• Because there is another whole unit we can go up in height.
