# Cuboid calculation

For cuboids those formulas hold:

base area = a*b

volume = a*b*c

surface=2*a*b + 2*a*c + 2*b*c

The diagonal from one corner to the opposite corner has the formula square root of (a²+b²+c²) as we can see by applying Pythagoras twice.

A cuboid is uniquely determined by three of its lengths.

If you want to see some examples, just enter your values above.

For further information, just move the mouse over one of the words below and the corresponding piece of the cuboid gets marked.
