## Quick Answer

Calculate the volume of various three-dimensional geometric shapes. Select your shape and input the dimensions to see volume calculations in multiple units.

## Definition

A volume calculator computes the three-dimensional space enclosed by a solid shape, such as a sphere, cylinder, cone, cube, rectangular prism, or pyramid. It utilizes geometric formulas corresponding to the selected shape, using parameters like radius or diameter, height, length, and width. Dimensions can be entered in inches, feet, yards, centimeters, or meters, and the volume is returned in the matching cubic unit, alongside the equivalent in cubic feet, cubic yards, and cubic meters wherever those differ from it. Builders, engineers, and landscapers use it to determine material requirements and container capacities.

## How to Use

1. **Select the three-dimensional shape** — Choose the type of solid shape you are analyzing from the shape selector menu.
2. **Input the physical dimensions** — Type the required measurements into the fields provided for that shape. Round shapes accept either a radius or a diameter.
3. **Read the volume results** — View the volume in your chosen cubic unit, the base area, and the equivalent in cubic feet, cubic yards, and cubic meters where those differ, along with the formula and the substituted working.
