Cuboid

A rectangular box is set by length, width, and height.

How it is calculated

The formulas assume right angles. A leaning box is not calculated this way.

V = abc, S = 2(ab + ac + bc), d = √(a² + b² + c²)

Where the numbers come from

  • Length
  • Width
  • Height

Example

Edges 2, 3, and 4. Volume 24, surface area 52, diagonal √29.

Questions

Does a cube work?

Yes, three equal edges. There is a separate cube calculator too.

The diagonal of a face, or the space diagonal?

The space diagonal, through the whole box.

Area of one face?

You can get it by multiplying two edges. The screen shows the sum of all six.
