Hi @PriscaTan!

Thanks very much for your kind contribution and changes! This is brilliant!
However, do you mind adding a description to your PR explaining the reason of adding “cube” to the calculator and describe a bit the few changes you have done?

Oh, and one more thing, on what Java version have you tested it?
Do you have a screenshot you could share showing this new button and response on the calculator?

Beside of this, everything else looks good 👍

Hey @PriscaTan 👋 let me know if you are still willing to finish this and get your PR merged? If not, I will close it.

Hi @PriscaTan, hope you are keeping well! Did you get the chance to see my comments? I'm about to close the PR.
