Let's look at the geometric attributes of a cube, but first please review the definition of Surface Area Of Three-Dimensional Shapes, Powers Definition, and Right Angle.

- A cube has some unique features, all sides are equal in length. For example, if one side (S) is three inches in length, the other three sides, length, width, and height are also three inches in length.
- Another unique feature of a cube, all sides are perpendicular to the side at its endpoints. This means all end-points of a Cube form a right angle.
- Special note, the
*side*of a cube must be greater than zero.

**Surface Area Of A Cube Formula**

Formula = (6 Sides To A Cube) × Area Of One Side (length × width) =

Formula = (6 Sides To A Cube) × Area Of One Side (S^{2}) =

Formula = (6) × S^{2} =

Formula = 6 × S^{2}
