To find the volume of the composite figure, we first need to find the volume of the rectangular prism and then add the volume of the cube.
Volume of rectangular prism = length x width x height
Volume of rectangular prism = 11 inches x 3 inches x 4 inches
Volume of rectangular prism = 132 cubic inches
Volume of cube = side x side x side
Volume of cube = 3 inches x 3 inches x 3 inches
Volume of cube = 27 cubic inches
Now, add the volumes together to find the total volume of the composite figure:
Total volume = 132 cubic inches + 27 cubic inches
Total volume = 159 cubic inches
Therefore, the volume of the composite figure is 159 cubic inches.
