i dont under stand how you find the area
The formula for the area of a square is (length x width) also denoted as base x height. A square specifically has all sides equal, as stated all four sides are 6 inches.
The area is calculated as 6 inches x 6 inches = 36 square inches = 36 in^{2}
If you are dealing with a 3 dimensional cube the above applies as the area of 1 side. The formula would be length x width x 6 because a cube has a total of 6 sides.
The area is calculated as 6 in x 6 in x 6 sides = 36 in^{2} x 6 = 216 in^{2}
