Volume Calculator for quick, reliable checks
Calculate volume for rectangular prisms, cylinders, spheres, and cones. Volume measures three-dimensional capacity in cubic units; selecting the correct solid determines which dimensions and constants the calculation uses.
When to use this volume calculator
Use it for containers, geometry homework, construction estimates, and volume comparisons. For real containers or bulk materials, treat the geometric volume as a baseline and account separately for wall thickness, unusable space, settlement, or overfill.
How the calculation works
Volume depends on solid shape: rectangular prism length x width x height, cylinder pi x radius squared x height, sphere 4/3 pi radius cubed, or cone one-third cylinder volume. Cylinder and cone formulas use the circular base area πr²; a cone has one third of the volume of a cylinder with the same base and height.
Variable explanations
Understand what each input and result means before calculating.
Shape
Enter shape carefully because this value directly affects the result.
Length
Enter length carefully because this value directly affects the result.
Width
Enter width carefully because this value directly affects the result.
Height
Enter height carefully because this value directly affects the result.
Radius
Enter radius carefully because this value directly affects the result.
