Frequently Asked Questions
How do you calculate the volume of a cube?
Cube the side length: V = a³. For example, a cube with side 5 has volume 125.
What is the space diagonal of a cube?
The space diagonal connects opposite vertices through the interior: d = a√3.
How do you find the surface area of a cube?
A cube has 6 equal square faces: S = 6a².
