The formula for finding the volume of a rectangular prism is length x width x height.
In this case, the length is 3 cubes (3 x 1 = 3 inches), the width is 2 cubes (2 x 1 = 2 inches), and the height is also 2 cubes (2 x 1 = 2 inches).
Therefore, the volume of the rectangular prism is 3 x 2 x 2 = 12 cubic inches.
Since the length, width, and height are all the same (1 inch), the volume can also be calculated as side x side x side, which is 12 x 12 x 12 = 1728 cubic inches.
So, the volume of the right rectangular prism made up of 12 cubes that are 1-inch on each side is 1728/1 = 1728.
Use the image to answer the question.
An illustration shows a rectangular prism made of cubes placed as 3 columns, 2 cubes high and 2 cubes deep.
A right rectangular prism is made up of 12 cubes that are 12 -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.
