Find the Surface Area box (6.5)(6.5)(6.5)

Math
h=6.5l=6.5w=6.5
The surface area of a box is equal to the sum of the areas of each side of the box.
2⋅(length)⋅(width)+2⋅(length)⋅(height)+2⋅(width)⋅(height)
Substitute the values of the length l=6.5, the width w=6.5, and the height h=6.5 into the formula.
