The expression s^2 is the area of a square, where s is the side length of the square. What does the expression (6x) ^2 represents

The surface area of the cube

Step-by-step explanation:

The area of the side of a square is s^2

A cube has six sides

We find the surface area by adding up the area of all the sides

SA = s^2+s^2+s^2+s^2+s^2+s^2

SA = 6s^2
