Frequently Asked Questions
How is a cube different from a cuboid?
A cube is a special case of a cuboid where all three dimensions (length, width, height) are equal. A cuboid calculator needs three separate measurements; a cube only needs one, the side length.
Why does this calculator only take side length as input?
A cube's side length determines every other measurement, so it is the simplest and most common starting point. If you know the volume, surface area, or a diagonal instead and want to work backward to the side length, use the perfect cube calculator or solve a^3 = volume directly.
What is a space diagonal?
The space diagonal (or cube diagonal) is the longest straight line that fits inside a cube, running from one corner through the interior to the opposite corner. It is longer than a face diagonal, which only crosses one flat face.
