Introduction
The Cubic Feet Calculator finds the volume of a rectangular box, room, shipment, container, or material area from length, width, and height.
For a rectangular shape, cubic feet equals length in feet multiplied by width in feet multiplied by height in feet. If dimensions are entered in another unit, the calculator converts them to feet first.
Formula and method guide
Cubic feet
Cubic Feet = Length(ft) x Width(ft) x Height(ft)
This is the standard rectangular volume formula.
Cubic yards
Cubic Yards = Cubic Feet / 27
This is useful for bulk materials such as soil, mulch, gravel, or concrete.
Cubic inches
Cubic Inches = Cubic Feet x 1,728
This helps compare measurements entered or reported in inches.
Variables
The longest side or front-to-back measurement.
The side-to-side measurement.
The vertical, depth, or thickness measurement.
The measurement unit used for the entered dimensions.
The number of identical boxes, spaces, or items.
