The volume of the rectangular prism is found with 7x4x212=5936
The volume of the cube is found with 12x12x12, because all the sides on a cube are equal= 1728
To find how many cubes fir in the rectangular prism, you divide the volumes
5936 divided by 1728= 3.435 when rounded to the nearest thousanth
