Jackie has stacked two layers of cubes. She knows that the yellow cubes are the same size as the red cubes. She also knows that the red layer has the following dimensions: Length= 3 over 2 ft, width= 1 ft, height= 1 over 2 ft.
If Jackie continues to stack layers of cubes, how many layers in all are needed to build a rectangular prism with a volume of 3 cubic feet?
