The document discusses doubling the volume of a rectangular prism. It asks students to find dimensions of a box that holds twice as many cubes as a 2 x 3 x 5 box. Students brainstorm ideas and watch a video on doubling volume. They then list different dimensions that satisfy doubling the volume, where some only double one dimension and the product of all dimensions is 60, using factors of 60 like 2, 4, 5.
