Today in class, we learned how to use rectangular prisms. And how to count the showing faces.The formula we used was 4n+2.The N represents the number of cubes we used. For every new cube that we added, there are 4 more faces added. Then, we multiplied 4 by the number of cubes because there are 4 sides of the cubes at https://casinoutanregistrering.org. We also added 2 because there were 2 faces on the videosxxx ends.
