How to use this table

Find the row closest to your edge length and read across to the volume. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Cube Calculator for a precise answer.

Need a value that is not in the table? — the Cube Calculator does it instantly, for free, with the formula and a worked example built in.

Frequently asked questions

Each cell is computed with the standard formula using exact arithmetic — the same calculation behind our Cube Calculator — so every figure is accurate for the stated assumptions.

Yes. The table covers common edge length values; for any exact figure, enter your own numbers in the Cube Calculator.
