Calculating Volume of Prisms

The video tutorial reviews questions from a unit test on the volume of rectangular prisms. It covers different methods to calculate volume, including using unit cubes and the volume formula. The tutorial also discusses expressions, the commutative property, and solving composite figure problems. A bonus question about an aquarium's water height is included, along with a sandbox problem. The video concludes with determining the number of cubes in a Rubik's cube.
