A triangular prism has a rectangular prism cut out of it from one base to the opposite base, as shown in the figure. All measurements are in millimeters.

1. What was the volume of the figure before the rectangular prism was cut out from it?
(The volume of the whole triangular prism)

2. What is the volume of the rectangular prism that is cut out?

3. What is the volume of the prism as it is shown in the picture?
