3/2 cubic meters
1/8 cubic meters
5/4 cubic meters
8 cubic meters

The volume of a cube is equal to the edge length cubed. Given that each cube has an edge length of 1/2 meter, the volume of one cube is (1/2)^3 = 1/8 cubic meters.

Since there are 10 cubes packed in the right rectangular prism, the total volume of the prism is 10 * 1/8 = 5/4 cubic meters.

Therefore, the correct answer is 5/4 cubic meters.
