A cube of length 7 cm is painted on all its faces. What is the total surface area of the painted surfaces?

294

Step-by-step explanation:

To find the surface area of a cube, first we need to realize that a cube, on its surface, is made up of 6 squares forming a box. That means that all we need to do is find the surface area of one of those squares, and multiply it by 6. So what we do is take side length 7, and square it, giving us 49. Then, we multiply that by 6 giving us 294. The formula for this, in short, is y=6a^2, y being the total surface area and a being a side length, in this case 7.

Hope this helps!! (and brainliest is always appreciated <3)

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
