Final answer:
To find the number of cubes in the rectangular prism with a volume of 6 cubic units and side lengths of 1/2 unit, divide the volume of the prism by the volume of each cube. The answer is 48 cubes.
Step-by-step explanation:
To find the number of cubes present in the rectangular prism, we need to divide the volume of the prism by the volume of each cube. The volume of the rectangular prism is 6 cubic units, and the volume of each cube is (1/2)^3 = 1/8 cubic units. So, the number of cubes present in the rectangular prism is 6 / (1/8) = 48 cubes.
