Cube Volume

How to use this calculator

1. Enter edge in cm.
2. Select Calculate and keep the output unit with the answer.

Before you use the answer

Start with a dimensioned sketch and label the units beside every measurement. Distinguish the outer edge from an internal opening, and distinguish a radius from a diameter. A geometric model is most useful when the shape actually matches the assumptions in the formula.

Doubling every edge multiplies the volume by eight.

Why might a result be approximate?

Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
