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.
Cube method:
Since each cube has a side length of 1/2 inch, the volume of each cube is (1/2)^3 = 1/8 cubic inches.
There are 12 cubes in the prism, so the total volume of the prism is 12 * 1/8 = 12/8 = 3/2 cubic inches.
Formula method:
The formula for the volume of a right rectangular prism is length x width x height.
In this case, the length, width, and height of the prism are all 1/2 inch.
Therefore, the volume of the prism is (1/2) x (1/2) x (1/2) = 1/8 cubic inches.
Both methods yield the same result: the volume of the prism is 3/2 cubic inches.
