Jim used 6 white cubes to make a rectangular prism. He painted the whole outside blue. If Jim separates the cubes, how many will have more blue faces than white. How many will have an equal number of blue and white faces
how are the cubes arranged? 1x6 or 2x3?
well i don't know the answer but the blocks are arranged like this

To determine the number of cubes that will have more blue faces than white, we first need to understand the structure of the rectangular prism.
Since Jim used 6 white cubes to create the rectangular prism, we know that there are 6 faces on the outside that can be painted blue. The rectangular prism has a total of 12 edges, and each edge is shared by two adjacent cubes. This means that there are 6 edges that are exposed and not shared with any other cubes.
To find the number of cubes that will have more blue faces than white, we count the number of cubes that have at least one exposed edge. Each of these cubes will have 1 face painted completely blue (the exposed face) and 2 faces painted partially blue (the faces adjacent to the exposed edge) out of the total 6 faces.
Since each of these cubes has 3 faces with blue paint, they will have more blue faces than white. Therefore, the number of cubes with more blue faces than white is equal to the number of cubes with at least one exposed edge, which is 6.
To find the number of cubes that will have an equal number of blue and white faces, we need to consider the remaining cubes that do not have any exposed edges. These cubes will have all 6 faces painted blue, resulting in an equal number of blue and white faces.
Therefore, the number of cubes with an equal number of blue and white faces is equal to the number of cubes minus the number of cubes with more blue faces than white. In this case, it is 6 cubes minus 6 cubes, which equals 0 cubes.
In summary:
- The number of cubes that will have more blue faces than white is 6.
- The number of cubes that will have an equal number of blue and white faces is 0.
