What is the volume of a cube?

Volume = side³. A cube with 5cm sides has volume = 125 cm³.

What is the surface area of a cube?

Surface Area = 6 × side². A cube has 6 identical square faces.

What is a space diagonal?

The space diagonal goes from one corner to the opposite corner through the center. d = side × √3.

What is a face diagonal?

A face diagonal goes across one face of the cube. d = side × √2.
