Carla formed this large cube from eight small cubes. She put the large cube on a worktable and then spray painted all the sides that she should without moving any part of the large cube. If she take the large cube apart, how many of the small cubes will be painted on three sides.
Consider that the large cube would be 2 by 2 by 2 small cubes. Draw the diagram of this arrangement. The bottom and inner portions will not be painted. Does that help you?
I think 4 sides because, carla cant spray paint the bottom so.....
To determine the number of small cubes that will be painted on three sides, we need to visualize how the large cube is formed using the small cubes.
A large cube is formed by stacking eight small cubes together. Since each small cube has six sides, each side of the large cube is made up of four small cubes.
To find the number of small cubes that will be painted on three sides, we need to identify how many of the small cubes are shared between three sides of the large cube.
When we inspect the corners of the large cube, we notice that each corner is a part of three sides of the cube. As there are eight corners in total, we can conclude that there are eight small cubes that will be painted on three sides.
Hence, when Carla takes the large cube apart, there will be eight small cubes that will be painted on three of their sides.
