____cubic inches
The volume of a right rectangular prism is found by multiplying the length, width, and height of the prism. In this case, the prism is 3 columns wide, 2 cubes high, and 2 cubes deep.
Volume = 3 x 2 x 2 = 12 cubic units
Since each cube has sides of 1/2 inch, the volume of the prism is 12 x (1/2)^3 = 12 x (1/8) = 12/8 = 3/2
Therefore, the volume of the right rectangular prism is 3/2 cubic inches.
