To find the volume of the rectangular prism, multiply the length, width, and height:
1/2 * 1/4 * 5/4 = 5/32 cubic meters
Now, to show that the product is the same as the volume found by packing the prism with 10 unit cubes with an edge length of 1/4 m:
10 * 1/4 * 1/4 * 1/4 = 10/64 = 5/32 cubic meters
Therefore, the volume of the prism is 5/32 cubic meters.
