To check the volume using the cube method, we need to find the edge length of the cubes that will fit into the rectangular prism.
The edge length of the cube will be the greatest common factor of the three dimensions of the rectangular prism: 1 1/3, 1, and 2/3.
1 1/3 = 4/3
2/3 = 2/3
The greatest common factor of 4/3, 1, and 2/3 is 1/3.
Therefore, the edge length of the cubes you will use is 1/3 inches.
Use the image to answer the question.
An illustration shows a 3 D rectangular cuboid with length of 1 start fraction 1 over 3 end fraction, a width of 1, and a height of start fraction 2 over 3 end fraction. The sides at the back that are not visible are shown as dashed lines.
You find the volume of the right rectangular prism using the formula method and want to check your answer using the cube method. What is the edge length of the cubes you will use? Lengths are given in inches. Provide your answer as a fraction reduced to the lowest terms.
