To find the volume of the rectangular prism, multiply the length, width, and height together:
(1/2) * (1/4) * (5/4) = 5/32
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 * 1/64 = 10/64 = 5/32
So, the volume of the rectangular prism is 5/32 cubic meters.
