A rectangular solid with the dimension 1m x 1m x 3m is divided into three equal cubes. How much is the surface area of this solid increased?

    you have added 2 sides at each juncture, or an additional area of 2*1+ 2*1 or 4m^2

  • Math and Science - ,

    So what does that mean? Sorry I don't understand. How do I find the percentage of increase?

  • Math and Science - ,

    percentage increase= 4m^2 over old surface area. Figure that out. add the total area for all six sides, and add. Draw a picture.
