To find the volume of the composite figure, we need to find the volume of the rectangular prism and the cube separately, and then add them together.
Volume of the rectangular prism:
Volume = length x width x height
Volume = 6 inches x 6 inches x 2 inches
Volume = 72 cubic inches
Volume of the cube:
Volume = side x side x side
Volume = 2 inches x 2 inches x 2 inches
Volume = 8 cubic inches
Total volume of the composite figure:
72 cubic inches (rectangle) + 8 cubic inches (cube) = 80 cubic inches
Therefore, the volume of the composite figure is 80 cubic inches.
