A right rectangular prism is made up of 12 cubes that are 1/2 inch on each side. Use the cube method or the formula method to find the volume. Provide your answer as an improper fraction reduced to the lowest terms.
Using the cube method, we can arrange the 12 cubes into a rectangular prism with dimensions 2 x 2 x 3.
The volume of a rectangular prism is calculated using the formula length x width x height. In this case, the volume is:
2 x 2 x 3 = 12
Therefore, the volume of the rectangular prism made up of 12 cubes that are 1/2 inch on each side is 12 cubic inches.
