About This Volume Calculator
Volume measures how much three-dimensional space an object occupies. This calculator supports three common shapes: rectangular boxes, cylinders, and spheres. It is useful for packaging, fluid containers, storage planning, school math, and engineering quick checks.
Tip: keep all inputs in the same unit to avoid conversion mistakes. If dimensions are in centimeters, the final output is cubic centimeters.

Volume Calculator FAQ
How do you calculate box volume?
Multiply length by width by height. Formula: V = l * w * h.
How do you calculate cylinder volume?
Multiply pi by radius squared and then by height. Formula: V = pi * r^2 * h.
How do you calculate sphere volume?
Multiply four-thirds by pi and radius cubed. Formula: V = (4/3) * pi * r^3.
What unit is the output in?
Volume uses cubic units based on your input unit. If your dimensions are in centimeters, the result is in cubic centimeters (cm^3).
