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. Understand and use the formula v = b · h, where in this case, b is the area of the base (b = l x w) to find volumes of right rectangular prisms with fractional edge lengths in mathematical problems and problems in real-world context
