Common Core Standard: 6.G.2 Find the volume of a right rectangular prism with fractional edge lengths by packing it with

unit cubes of the appropriate unit fraction edge lengths, and show that the volume is the same as would be found by

multiplying the edge lengths of the prism. Apply the formulas V = l w h and V = b h to find volumes of right rectangular

prisms with fractional edge lengths in the context of solving real-world and mathematical problems.
