Cuboid volume (interactive layering)

Scroll through the first few slides to introduce a cuboid (hover over the pictures to reveal the properties and click on the boy pushing over the rectangle to revel transform a rectangle into a cuboid). Break down the layers of the cuboid examples by clicking on the x, y, z buttons to see the layers separate and questions students on the associated multiplications and the commutative properties of multiplication. When the cubes can't be seen, hover over the faces of the cuboid examples to reveal the cubes and click the covers to reveal the answers.
