How volume is calculated
Volume measures three-dimensional space. The formula depends on the shape being measured.
Rectangular prism: V = L × W × H
Volume example
A rectangular space measuring 4 ft × 3 ft × 2 ft has a volume of 24 cubic feet.
Frequently asked questions
What is cubic feet?
Cubic feet is a unit of volume representing a cube one foot on each side.
How many cubic feet are in one cubic yard?
27 cubic feet.
Is area the same as volume?
No. Area is two-dimensional, while volume includes length, width and height.
Using this calculator effectively
This calculator gives geometric volume for a rectangular prism or cylinder using the dimensions you enter. It is useful when a project needs cubic measurement rather than surface area.
Common uses
- Finding the capacity of a simple box-shaped space.
- Estimating the volume of a cylindrical container or column.
- Converting a cubic-foot result into cubic yards for rough material planning.
Tips for a better estimate
- Measure every dimension using the same length unit before calculating.
- Use radius, not diameter, for the cylindrical calculation.
- For irregular shapes, divide the object into simpler sections and calculate them separately.
