The Volume of a Box calculator computes 
Box aka Parallelepiped the volume of a box (a.k.a. rectangular parallelepiped) based on the length, height and depth (see diagram).
INSTRUCTIONS: Choose units and enter the following:
- (l) length of box
- (h) height of box
- (d) depth of box
Volume of a Box (V): The volume is returned in cubic meters. However, this can be automatically converted into many other volume units (e.g. cubic feet, gallons, litres) via the pull-down menu.
The Math / Science
A box is three dimensional volume with perpendicular corners. A special case of the box is a cube where all dimensions are the same. A box shape is very common in construction and other manufacturing due to the ease in establishing consistency and in stacking and measuring.
The formula for the volume of a box (parallelepiped) is:
V = L • H • D
where:
- V is the volume of box
- L is the length
- H is the height
- D is the depth

Volume is a three dimensional measurement of the amount of space taken up by an object. 
Volume units are cubic measurements for solid objects such as cubic inches and cubic meters. Fluids have separate volume units such as liters, fluid ounces, cups, gallons, and barrel.
The volume of an object can measured by the liquid it displaces or be calculated by measuring its dimensions and applying those dimensions to a formula describing its shape. Many such calculations are available in the following list of calculators.
In many cases, the calculators are for a column with a geometric shaped base and vertical sides. One basic formula for volume is area times a Height when the volume has vertical sides.
